Question 1

Liam is thinking of a fraction that is greater than 25\frac{2}{5} and less than 23\frac{2}{3}. Which fraction could Liam be thinking of?

  1. 13\frac{1}{3}
  2. 34\frac{3}{4}
  3. 12\frac{1}{2} (correct answer)
  4. 45\frac{4}{5}
Explanation: We need to find a fraction between 25\frac{2}{5} and 23\frac{2}{3}. Let's find a common denominator for the given fractions and the answer choices. A common denominator for 5, 3, 4, 2 is 60.\n\n* The lower bound is 25=2×125×12=2460\frac{2}{5} = \frac{2 \times 12}{5 \times 12} = \frac{24}{60}.\n* The upper bound is 23=2×203×20=4060\frac{2}{3} = \frac{2 \times 20}{3 \times 20} = \frac{40}{60}.\n\nWe need to find a fraction between 2460\frac{24}{60} and 4060\frac{40}{60}.\n\n* (A) 13=2060\frac{1}{3} = \frac{20}{60}. This is less than 2460\frac{24}{60}.\n* (B) 34=4560\frac{3}{4} = \frac{45}{60}. This is greater than 4060\frac{40}{60}.\n* (C) 12=3060\frac{1}{2} = \frac{30}{60}. This is between 2460\frac{24}{60} and 4060\frac{40}{60}.\n* (D) 45=4860\frac{4}{5} = \frac{48}{60}. This is greater than 4060\frac{40}{60}.\n\nTherefore, the fraction Liam could be thinking of is 12\frac{1}{2}.

Question 2

There are four boxes of crayons. Box A is 23\frac{2}{3} full. Box B is 35\frac{3}{5} full. Box C is 12\frac{1}{2} full. Box D is fuller than Box B but less full than Box A. Which fraction could represent how full Box D is?

  1. 47\frac{4}{7}
  2. 58\frac{5}{8} (correct answer)
  3. 34\frac{3}{4}
  4. 710\frac{7}{10}
Explanation: We are looking for a fraction between 35\frac{3}{5} (Box B) and 23\frac{2}{3} (Box A). Let's convert these to decimals to make comparison easier.\n\n* 35=0.6\frac{3}{5} = 0.6\n* 230.667\frac{2}{3} \approx 0.667\n\nWe need to find an answer choice with a value between 0.6 and 0.667.\n\n* (A) 470.571\frac{4}{7} \approx 0.571. This is less than 0.6.\n* (B) 58=0.625\frac{5}{8} = 0.625. This is between 0.6 and 0.667.\n* (C) 34=0.75\frac{3}{4} = 0.75. This is greater than 0.667.\n* (D) 710=0.7\frac{7}{10} = 0.7. This is greater than 0.667.\n\nThe fraction 58\frac{5}{8} is the only one that falls between 35\frac{3}{5} and 23\frac{2}{3}.

Question 3

Mr. Chen's class is collecting canned goods for a food drive. They collected more than 2132\frac{1}{3} boxes but fewer than 2122\frac{1}{2} boxes. Which of the following amounts could they have collected?

  1. 2142\frac{1}{4} boxes
  2. 2252\frac{2}{5} boxes (correct answer)
  3. 2352\frac{3}{5} boxes
  4. 2162\frac{1}{6} boxes
Explanation: The whole number part of the mixed numbers is 2 for both boundaries and all answer choices, so we only need to compare the fractional parts. We need to find a fraction that is between 13\frac{1}{3} and 12\frac{1}{2}.\nLet's convert 13\frac{1}{3} and 12\frac{1}{2} to decimals to compare: 130.333\frac{1}{3} \approx 0.333 and 12=0.5\frac{1}{2} = 0.5. We are looking for a fraction between 0.333 and 0.5.\n\n* (A) The fractional part is 14=0.25\frac{1}{4} = 0.25, which is less than 0.333.\n* (B) The fractional part is 25=0.4\frac{2}{5} = 0.4, which is between 0.333 and 0.5.\n* (C) The fractional part is 35=0.6\frac{3}{5} = 0.6, which is greater than 0.5.\n* (D) The fractional part is 160.167\frac{1}{6} \approx 0.167, which is less than 0.333.\n\nTherefore, the class could have collected 2252\frac{2}{5} boxes.

Question 4

A pitcher contains some water. The amount of water is more than 34\frac{3}{4} of a liter but less than 45\frac{4}{5} of a liter. Which could be the amount of water in the pitcher?

  1. 3140\frac{31}{40} liter (correct answer)
  2. 23\frac{2}{3} liter
  3. 1520\frac{15}{20} liter
  4. 710\frac{7}{10} liter
Explanation: When you see a problem asking which value falls within a given range, you need to compare fractions by finding a common way to evaluate them all. The water amount must be between 34\frac{3}{4} and 45\frac{4}{5} of a liter. To compare these fractions with the answer choices, convert everything to decimals or find a common denominator. Using decimals: 34=0.75\frac{3}{4} = 0.75 and 45=0.80\frac{4}{5} = 0.80, so you need a value between 0.75 and 0.80. Let's check each option: Choice A: 3140=0.775\frac{31}{40} = 0.775. This falls perfectly between 0.75 and 0.80, so this works. Choice B: 23=0.667\frac{2}{3} = 0.667. This is less than 0.75, so it's too small to be in our range. Choice C: 1520=34=0.75\frac{15}{20} = \frac{3}{4} = 0.75. The problem states the amount must be more than 34\frac{3}{4}, so this exact value doesn't qualify. Choice D: 710=0.70\frac{7}{10} = 0.70. This is also less than 0.75, making it too small. Only choice A gives us a value that's actually between the two boundaries, not equal to them or outside the range. Strategy tip: When comparing fractions, converting to decimals often makes the relationships clearer than finding common denominators. Also, pay close attention to whether the problem uses "more than/less than" versus "at least/at most" — this determines whether boundary values are included.

Question 5

Jenny's house is 58\frac{5}{8} of a mile from school. Leo's house is 34\frac{3}{4} of a mile from school. A park is located at a distance from the school that is between Jenny's and Leo's distances. Which could be the park's distance from the school?

  1. 12\frac{1}{2} mile
  2. 916\frac{9}{16} mile
  3. 1116\frac{11}{16} mile (correct answer)
  4. 78\frac{7}{8} mile
Explanation: We need to find a fraction between 58\frac{5}{8} and 34\frac{3}{4}. Let's convert the fractions to have a common denominator, such as 16.\n\n* Jenny's distance: 58=5×28×2=1016\frac{5}{8} = \frac{5 \times 2}{8 \times 2} = \frac{10}{16} mile.\n* Leo's distance: 34=3×44×4=1216\frac{3}{4} = \frac{3 \times 4}{4 \times 4} = \frac{12}{16} mile.\n\nThe park's distance must be between 1016\frac{10}{16} and 1216\frac{12}{16} of a mile. Let's check the answer choices.\n\n* (A) 12=816\frac{1}{2} = \frac{8}{16}, which is less than 1016\frac{10}{16}.\n* (B) 916\frac{9}{16} is less than 1016\frac{10}{16}.\n* (C) 1116\frac{11}{16} is between 1016\frac{10}{16} and 1216\frac{12}{16}.\n* (D) 78=1416\frac{7}{8} = \frac{14}{16}, which is greater than 1216\frac{12}{16}.\n\nThe correct answer is 1116\frac{11}{16} mile.

Question 6

Three friends ran part of a mile. Maria ran 512\frac{5}{12} of a mile. Sam ran 38\frac{3}{8} of a mile. Chloe ran a distance that was between Maria's distance and Sam's distance. What could have been the distance Chloe ran?

  1. 13\frac{1}{3} mile
  2. 1948\frac{19}{48} mile (correct answer)
  3. 716\frac{7}{16} mile
  4. 12\frac{1}{2} mile
Explanation: First, we need to compare the distances run by Maria and Sam to determine the range for Chloe's distance. We'll use a common denominator for 512\frac{5}{12} and 38\frac{3}{8}. The least common multiple of 12 and 8 is 24.\n\n* Maria's distance: 512=5×212imes2=1024\frac{5}{12} = \frac{5 \times 2}{12 imes 2} = \frac{10}{24} mile.\n* Sam's distance: 38=3×38×3=924\frac{3}{8} = \frac{3 \times 3}{8 \times 3} = \frac{9}{24} mile.\n\nChloe's distance is between 924\frac{9}{24} and 1024\frac{10}{24}. To find a fraction between these, we can use a larger common denominator, like 48.\n\n* Sam: 924=1848\frac{9}{24} = \frac{18}{48}. Maria: 1024=2048\frac{10}{24} = \frac{20}{48}.\n\nChloe's distance is between 1848\frac{18}{48} and 2048\frac{20}{48}. Let's check the choices.\n\n* (A) 13=1648\frac{1}{3} = \frac{16}{48}, which is less than 1848\frac{18}{48}.\n* (B) 1948\frac{19}{48} is between 1848\frac{18}{48} and 2048\frac{20}{48}.\n* (C) 716=2148\frac{7}{16} = \frac{21}{48}, which is greater than 2048\frac{20}{48}.\n* (D) 12=2448\frac{1}{2} = \frac{24}{48}, which is greater than 2048\frac{20}{48}.

Question 7

A recipe for a fruit smoothie calls for an amount of yogurt that is more than 23\frac{2}{3} cup but less than 34\frac{3}{4} cup. Which of the following amounts of yogurt could be used in the recipe?

  1. 12\frac{1}{2} cup
  2. 58\frac{5}{8} cup
  3. 710\frac{7}{10} cup (correct answer)
  4. 56\frac{5}{6} cup
Explanation: To solve this problem, we need to find a fraction that is between 23\frac{2}{3} and 34\frac{3}{4}. A good way to compare these fractions is to find a common denominator. The least common multiple of 3, 4, and the denominators in the answer choices (2, 8, 10, 6) is 120. Let's convert the given fractions and the choices to have a denominator of 120.\n\n* The lower bound is 23=2×403×40=80120\frac{2}{3} = \frac{2 \times 40}{3 \times 40} = \frac{80}{120}.\n* The upper bound is 34=3×304×30=90120\frac{3}{4} = \frac{3 \times 30}{4 \times 30} = \frac{90}{120}.\n\nWe need to find a fraction between 80120\frac{80}{120} and 90120\frac{90}{120}.\n\n* (A) 12=60120\frac{1}{2} = \frac{60}{120}, which is less than 80120\frac{80}{120}.\n* (B) 58=5×158×15=75120\frac{5}{8} = \frac{5 \times 15}{8 \times 15} = \frac{75}{120}, which is less than 80120\frac{80}{120}.\n* (C) 710=7×1210×12=84120\frac{7}{10} = \frac{7 \times 12}{10 \times 12} = \frac{84}{120}, which is between 80120\frac{80}{120} and 90120\frac{90}{120}.\n* (D) 56=5×206×20=100120\frac{5}{6} = \frac{5 \times 20}{6 \times 20} = \frac{100}{120}, which is greater than 90120\frac{90}{120}.\n\nTherefore, 710\frac{7}{10} cup is a valid amount.

Question 8

Sarah has a piece of ribbon that is longer than 14\frac{1}{4} yard but shorter than the total length of a 13\frac{1}{3} yard piece and a 16\frac{1}{6} yard piece combined. Which of the following could be the length of Sarah's ribbon?

  1. 15\frac{1}{5} yard
  2. 25\frac{2}{5} yard (correct answer)
  3. 35\frac{3}{5} yard
  4. 16\frac{1}{6} yard
Explanation: First, we need to find the upper boundary for the ribbon's length by adding 13\frac{1}{3} and 16\frac{1}{6}. To add these, we need a common denominator, which is 6.\n\n13+16=26+16=36=12\frac{1}{3} + \frac{1}{6} = \frac{2}{6} + \frac{1}{6} = \frac{3}{6} = \frac{1}{2} yard.\n\nThe ribbon's length is between 14\frac{1}{4} yard and 12\frac{1}{2} yard. We can convert these to decimals to compare: 14=0.25\frac{1}{4} = 0.25 and 12=0.5\frac{1}{2} = 0.5. We need to find which answer choice falls between 0.25 and 0.5.\n\n* (A) 15=0.2\frac{1}{5} = 0.2, which is less than 0.25.\n* (B) 25=0.4\frac{2}{5} = 0.4, which is between 0.25 and 0.5.\n* (C) 35=0.6\frac{3}{5} = 0.6, which is greater than 0.5.\n* (D) 160.167\frac{1}{6} \approx 0.167, which is less than 0.25.\n\nThe correct answer is 25\frac{2}{5} yard.

Question 9

Three of the following fractions have a value between 15\frac{1}{5} and 35\frac{3}{5}. Which fraction does NOT have a value between 15\frac{1}{5} and 35\frac{3}{5}?

  1. 14\frac{1}{4}
  2. 13\frac{1}{3}
  3. 12\frac{1}{2}
  4. 23\frac{2}{3} (correct answer)
Explanation: We need to compare each answer choice to the given range of 15\frac{1}{5} to 35\frac{3}{5}. Using decimals can be helpful here: 15=0.2\frac{1}{5} = 0.2 and 35=0.6\frac{3}{5} = 0.6. The question asks for the fraction that is NOT between 0.2 and 0.6.\n\n* (A) 14=0.25\frac{1}{4} = 0.25. This is between 0.2 and 0.6.\n* (B) 130.333\frac{1}{3} \approx 0.333. This is between 0.2 and 0.6.\n* (C) 12=0.5\frac{1}{2} = 0.5. This is between 0.2 and 0.6.\n* (D) 230.666\frac{2}{3} \approx 0.666. This is greater than 0.6.\n\nTherefore, 23\frac{2}{3} is the fraction that is not between 15\frac{1}{5} and 35\frac{3}{5}.

Question 10

Which of the following fractions has a value between 0.650.65 and 0.80.8?

  1. 35\frac{3}{5}
  2. 45\frac{4}{5}
  3. 23\frac{2}{3} (correct answer)
  4. 58\frac{5}{8}
Explanation: We need a fraction with a decimal value between 0.65 and 0.8. Let's convert each answer choice to a decimal.\n\n* (A) 35=0.6\frac{3}{5} = 0.6, which is less than 0.65.\n* (B) 45=0.8\frac{4}{5} = 0.8, which is equal to the upper boundary, not between the boundaries.\n* (C) 23=2÷30.667\frac{2}{3} = 2 \div 3 \approx 0.667, which is between 0.65 and 0.8.\n* (D) 58=5÷8=0.625\frac{5}{8} = 5 \div 8 = 0.625, which is less than 0.65.\n\nTherefore, 23\frac{2}{3} is the only fraction that falls between 0.65 and 0.8.

Question 11

A chocolate bar is divided into 12 equal squares. Maya eats more than 14\frac{1}{4} of the bar but less than 12\frac{1}{2} of the bar. How many squares could Maya have eaten?

  1. 3
  2. 5 (correct answer)
  3. 6
  4. 7
Explanation: First, we need to determine the number of squares that represent 14\frac{1}{4} and 12\frac{1}{2} of the 12-square bar.\n\n* The lower limit is 14\frac{1}{4} of 12, which is 14×12=3\frac{1}{4} \times 12 = 3 squares.\n* The upper limit is 12\frac{1}{2} of 12, which is 12×12=6\frac{1}{2} \times 12 = 6 squares.\n\nThe problem states that Maya ate more than 3 squares and less than 6 squares. This means the number of squares eaten must be a whole number greater than 3 and less than 6. The possible whole numbers are 4 and 5.\n\nLooking at the answer choices:\n* (A) 3 is not more than 3.\n* (B) 5 is a possible number of squares.\n* (C) 6 is not less than 6.\n* (D) 7 is more than 6.\n\nTherefore, Maya could have eaten 5 squares.

Question 12

Which of the following fractions is between 27\frac{2}{7} and 25\frac{2}{5}?

  1. 29\frac{2}{9}
  2. 14\frac{1}{4}
  3. 12\frac{1}{2}
  4. 13\frac{1}{3} (correct answer)
Explanation: We are looking for a fraction between 27\frac{2}{7} and 25\frac{2}{5}. When comparing fractions with the same numerator (in this case, 2), the fraction with the smaller denominator is larger. So, 25\frac{2}{5} is larger than 27\frac{2}{7}. We need a fraction, let's call it 2x\frac{2}{x}, where the denominator x is between 5 and 7. The whole number between 5 and 7 is 6. So, the fraction 26\frac{2}{6} is between 27\frac{2}{7} and 25\frac{2}{5}. The fraction 26\frac{2}{6} simplifies to 13\frac{1}{3}.\nLet's check the choices:\n(A) 29\frac{2}{9}: Since 9 is greater than 7, 29\frac{2}{9} is less than 27\frac{2}{7}.\n(B) 14=28\frac{1}{4} = \frac{2}{8}: Since 8 is greater than 7, 28\frac{2}{8} is less than 27\frac{2}{7}.\n(C) 12=24\frac{1}{2} = \frac{2}{4}: Since 4 is less than 5, 24\frac{2}{4} is greater than 25\frac{2}{5}.\n(D) 13=26\frac{1}{3} = \frac{2}{6}: Since 6 is between 5 and 7, 26\frac{2}{6} is between 27\frac{2}{7} and 25\frac{2}{5}.

Question 13

The fraction 49\frac{4}{9} is between which of the following pairs of fractions?

  1. 13\frac{1}{3} and 25\frac{2}{5}
  2. 25\frac{2}{5} and 12\frac{1}{2} (correct answer)
  3. 12\frac{1}{2} and 35\frac{3}{5}
  4. 38\frac{3}{8} and 716\frac{7}{16}
Explanation: We need to check each pair of fractions to see if 49\frac{4}{9} lies between them. Using decimals is an efficient method. 49=4÷90.444\frac{4}{9} = 4 \div 9 \approx 0.444.\n\n(A) 130.333\frac{1}{3} \approx 0.333 and 25=0.4\frac{2}{5} = 0.4. The number 0.444 is not between 0.333 and 0.4.\n(B) 25=0.4\frac{2}{5} = 0.4 and 12=0.5\frac{1}{2} = 0.5. The number 0.444 is between 0.4 and 0.5. This is the correct answer.\n(C) 12=0.5\frac{1}{2} = 0.5 and 35=0.6\frac{3}{5} = 0.6. The number 0.444 is not between 0.5 and 0.6.\n(D) 38=0.375\frac{3}{8} = 0.375 and 716=0.4375\frac{7}{16} = 0.4375. The number 0.444 is not between 0.375 and 0.4375.\n\nTherefore, 49\frac{4}{9} is between 25\frac{2}{5} and 12\frac{1}{2}.

Question 14

A plant grew more than 310\frac{3}{10} of a meter but less than 45\frac{4}{5} of a meter in one month. Which of the following could be the growth of the plant?

  1. 15\frac{1}{5} meter
  2. 910\frac{9}{10} meter
  3. 14\frac{1}{4} meter
  4. 23\frac{2}{3} meter (correct answer)
Explanation: We need to find a fraction that lies between 310\frac{3}{10} and 45\frac{4}{5}. First, let's make the denominators the same for the boundary fractions. The least common multiple of 10 and 5 is 10.\n\n45=4×25×2=810\frac{4}{5} = \frac{4 \times 2}{5 \times 2} = \frac{8}{10}\n\nSo, the plant's growth is between 310\frac{3}{10} and 810\frac{8}{10}. Now we check the answer choices.\n\n* (A) 15=210\frac{1}{5} = \frac{2}{10}. This is less than 310\frac{3}{10}.\n* (B) 910\frac{9}{10}. This is greater than 810\frac{8}{10}.\n* (C) 14\frac{1}{4}. To compare with 310\frac{3}{10}, we can use cross-multiplication: 1×10=101 \times 10 = 10 and 4×3=124 \times 3 = 12. Since 10<1210 < 12, 14<310\frac{1}{4} < \frac{3}{10}.\n* (D) 23\frac{2}{3}. To compare with 310\frac{3}{10}, cross-multiply: 2×10=202 \times 10 = 20 and 3×3=93 \times 3 = 9. Since 20>920 > 9, 23>310\frac{2}{3} > \frac{3}{10}. To compare with 810\frac{8}{10} (or 45\frac{4}{5}), cross-multiply: 2×5=102 \times 5 = 10 and 3×4=123 \times 4 = 12. Since 10<1210 < 12, 23<45\frac{2}{3} < \frac{4}{5}. So, 23\frac{2}{3} is between the two fractions.

Question 15

What fraction is exactly halfway between 13\frac{1}{3} and 12\frac{1}{2}?

  1. 25\frac{2}{5}
  2. 14\frac{1}{4}
  3. 38\frac{3}{8}
  4. 512\frac{5}{12} (correct answer)
Explanation: To find the fraction exactly halfway between two numbers, we find their average. This means we add the two fractions and then divide the sum by 2.\n\nStep 1: Add the fractions.

  3. 23\frac{2}{3} (correct answer)
  4. 78\frac{7}{8}
Explanation: To find a fraction between 38\frac{3}{8} and 56\frac{5}{6}, we should first convert them to fractions with a common denominator. The least common multiple of 8 and 6 is 24.\n\n* 38=3×38×3=924\frac{3}{8} = \frac{3 \times 3}{8 \times 3} = \frac{9}{24}\n* 56=5×46×4=2024\frac{5}{6} = \frac{5 \times 4}{6 \times 4} = \frac{20}{24}\n\nNow we need to find which answer choice is between 924\frac{9}{24} and 2024\frac{20}{24}. Let's convert the answer choices to have a denominator of 24.\n\n* (A) 13=1×83×8=824\frac{1}{3} = \frac{1 \times 8}{3 \times 8} = \frac{8}{24}. This is less than 924\frac{9}{24}.\n* (B) 14=1×64×6=624\frac{1}{4} = \frac{1 \times 6}{4 \times 6} = \frac{6}{24}. This is less than 924\frac{9}{24}.\n* (C) 23=2×83×8=1624\frac{2}{3} = \frac{2 \times 8}{3 \times 8} = \frac{16}{24}. This is between 924\frac{9}{24} and 2024\frac{20}{24}.\n* (D) 78=7×38×3=2124\frac{7}{8} = \frac{7 \times 3}{8 \times 3} = \frac{21}{24}. This is greater than 2024\frac{20}{24}.\n\nThe correct answer is 23\frac{2}{3}.

Question 17

Which fraction has a value between 47\frac{4}{7} and 58\frac{5}{8}?

  1. 12\frac{1}{2}
  2. 914\frac{9}{14}
  3. 23\frac{2}{3}
  4. 1728\frac{17}{28} (correct answer)
Explanation: To find a fraction between 47\frac{4}{7} and 58\frac{5}{8}, we must first compare them using a common denominator. The least common multiple of 7 and 8 is 56.\n\n* 47=4×87×8=3256\frac{4}{7} = \frac{4 \times 8}{7 \times 8} = \frac{32}{56}\n* 58=5×78×7=3556\frac{5}{8} = \frac{5 \times 7}{8 \times 7} = \frac{35}{56}\n\nWe are looking for a fraction with a value between 3256\frac{32}{56} and 3556\frac{35}{56}. Now, we convert the answer choices to have a denominator of 56.\n\n* (A) 12=2856\frac{1}{2} = \frac{28}{56}. This is less than 3256\frac{32}{56}.\n* (B) 914=9×414×4=3656\frac{9}{14} = \frac{9 \times 4}{14 \times 4} = \frac{36}{56}. This is greater than 3556\frac{35}{56}.\n* (C) 23=23×565637.356\frac{2}{3} = \frac{2}{3} \times \frac{56}{56} \approx \frac{37.3}{56}. This is greater than 3556\frac{35}{56}.\n* (D) 1728=17×228×2=3456\frac{17}{28} = \frac{17 \times 2}{28 \times 2} = \frac{34}{56}. This is between 3256\frac{32}{56} and 3556\frac{35}{56}.\n\nThus, 1728\frac{17}{28} is the correct answer.

Question 18

Which of the following fractions is greater than 18\frac{1}{8} but less than 16\frac{1}{6}?

  1. 748\frac{7}{48} (correct answer)
  2. 110\frac{1}{10}
  3. 14\frac{1}{4}
  4. 548\frac{5}{48}
Explanation: When comparing fractions, you need to determine which values fall between two given boundaries. Here, you're looking for a fraction between 18\frac{1}{8} and 16\frac{1}{6}. The most efficient approach is to convert all fractions to a common denominator. Since you're comparing with 18\frac{1}{8} and 16\frac{1}{6}, and several answer choices have denominator 48, let's use 48 as our common denominator. First, convert the boundaries: 18=648\frac{1}{8} = \frac{6}{48} and 16=848\frac{1}{6} = \frac{8}{48}. So you need a fraction between 648\frac{6}{48} and 848\frac{8}{48}. Choice A, 748\frac{7}{48}, falls perfectly between these values since 6<7<86 < 7 < 8. This means 648<748<848\frac{6}{48} < \frac{7}{48} < \frac{8}{48}, confirming that 748\frac{7}{48} is between 18\frac{1}{8} and 16\frac{1}{6}. Choice B, 110=4.848\frac{1}{10} = \frac{4.8}{48}, is less than 648\frac{6}{48}, making it smaller than 18\frac{1}{8}. Choice C, 14=1248\frac{1}{4} = \frac{12}{48}, is much larger than 848\frac{8}{48}, exceeding 16\frac{1}{6}. Choice D, 548\frac{5}{48}, is less than 648\frac{6}{48}, so it's also smaller than 18\frac{1}{8}. Strategy tip: When comparing fractions with different denominators, convert to a common denominator first. Look for the largest denominator among your choices—it often works well as your common denominator and simplifies the comparison process.
