2. ≈

3. (correct answer)
4. <

Question 4

1. $\frac{1}{4}$ (correct answer)
2. They are equal
3. Not enough information
4. $\frac{2}{9}$

Question 5

1. Cannot compare because 11 is larger than 5.
2. #ERROR!
3. < (correct answer)

Question 6

1. Monday
2. They ran equal distances
3. Tuesday (correct answer)
4. Cannot be determined without a common denominator

Question 7

1. $\frac{7}{10} > \frac{2}{3}$ because $\frac{21}{30} > \frac{20}{30}$ with a common denominator of 30 (correct answer)
2. $\frac{2}{3} > \frac{7}{10}$ because $\frac{20}{30} > \frac{21}{30}$ with a common denominator of 30
3. $\frac{7}{10} = \frac{2}{3}$ because both fractions are less than 1 whole
4. $\frac{7}{10} > \frac{2}{3}$ because $7 + 10 = 17$ is greater than $2 + 3 = 5$

Question 8

1. $\frac{1}{3} > \frac{3}{10}$ (correct answer)
2. $\frac{1}{3} < \frac{3}{10}$
3. $\frac{1}{3} = \frac{3}{10}$
4. $\frac{1}{3}$ and $\frac{3}{10}$ cannot be compared because their denominators are different.

Question 9

1. Maria ate more pizza
2. Jake ate more pizza (correct answer)
3. They ate the same amount
4. It cannot be determined

Question 10

1. Math class, because $\frac{4}{7} > \frac{3}{5}$ when converted to thirty-fifths: $\frac{20}{35} > \frac{21}{35}$
2. They are equal amounts because $\frac{4}{7}$ and $\frac{3}{5}$ both equal $\frac{12}{21}$ when simplified
3. Math class, because 4 is greater than 3 in the numerators of the fractions
4. Science class, because $\frac{3}{5} > \frac{4}{7}$ when converted to thirty-fifths: $\frac{21}{35} > \frac{20}{35}$ (correct answer)

Question 11

1. $\frac{3}{5} < \frac{7}{12}$
2. $\frac{3}{5} > \frac{7}{12}$ (correct answer)
3. $\frac{3}{5} = \frac{7}{12}$
4. Cannot be compared

Question 12

1. $\frac{4}{6} > \frac{5}{8}$ because $\frac{16}{24} > \frac{15}{24}$ when using equivalent fractions (correct answer)
2. $\frac{5}{8} > \frac{4}{6}$ because $\frac{15}{24} > \frac{16}{24}$ when using equivalent fractions
3. $\frac{4}{6} = \frac{5}{8}$ because both fractions are greater than $\frac{1}{2}$ of their wholes
4. $\frac{5}{8} > \frac{4}{6}$ because 5 parts is more than 4 parts in any rectangle

Question 13

1. $>$, because $\frac{2}{3} = \frac{6}{9}$ and $\frac{6}{9} > \frac{5}{9}$ (correct answer)
2. $<$, because $\frac{2}{3} = \frac{6}{9}$ and $\frac{6}{9} < \frac{5}{9}$
3. $=$, because $\frac{2}{3}$ and $\frac{5}{9}$ simplify to the same fraction
4. $<$, because comparing only the numerators, $2 < 5$

Question 14

1. < (correct answer)
3. #ERROR!
4. ≥

Question 15

1. $\frac{3}{8} > \frac{5}{12}$
2. $\frac{5}{12} = \frac{3}{8}$
3. $\frac{5}{12} > \frac{3}{8}$ (correct answer)
4. It cannot be determined without more information

Question 16

1. Maya painted more because $\frac{5}{8} > \frac{3}{4}$ when both are converted to eighths
2. Maya painted more because she used 5 parts while Carlos only used 3 parts
3. They painted equal amounts because $\frac{5}{8} = \frac{3}{4}$ when simplified to lowest terms
4. Carlos painted more because $\frac{3}{4} > \frac{5}{8}$ when both are converted to eighths (correct answer)
