Question 1

1. Only Alex, because $\frac{7}{8} \times 32 = 7 \times \frac{32}{8} = 7 \times 4$
2. Only Beth, because $\frac{7}{8} \times 32 = \frac{7 \times 32}{8}$ by definition
3. Alex and Carlos, because both partition $32$ first, then take $7$ parts
4. All three students, because they represent equivalent mathematical operations (correct answer)

Question 2

1. It means add 28 minutes 5 times because the numerator tells how many times to add.

3. It means divide 28 minutes into 7 equal parts and then take 5 of those parts. (correct answer)
4. It means the result must be more than 28 minutes because you are multiplying.

Question 3

1. It is found by dividing 16 kilometers into 4 equal parts and taking 1 part.
2. It equals 4 kilometers because one-fourth of 16 is one of the four equal parts.
3. It means adding 16 kilometers one-fourth of a time, which is not possible, so the expression has no meaning. (correct answer)
4. It is less than 16 kilometers because it is only part of the total plan.

Question 4

1. It represents 18 batteries because 21 is divided into 7 equal parts and you take 6 of those parts. (correct answer)
2. It represents 27 batteries because multiplying by 6 makes the number bigger.
3. It represents 3 batteries because 21 divided by 7 is 3 and you stop there.
4. It represents 24.5 batteries because $21 \div \frac{6}{7}=24.5$.

Question 5

1. It means you divide 30 into 6 equal groups and count 1 group.
2. It means the answer is 30 ÷ 6 books.

Question 6

1. It represents the length of ribbon in 2 of the 3 equal parts when 12 feet is divided into 3 equal parts. (correct answer)
2. It represents the length of ribbon when 2 feet are added 3 times.
3. It represents the length of ribbon in 2 parts when 12 feet is divided into 2 equal parts.
4. It represents the number of feet in $12\div\frac{2}{3}$ because multiplying by a fraction is the same as dividing by that fraction.

Question 7

1. Divide 16 meters into 8 equal sections, then find the total length of 5 of those sections. (correct answer)
2. Divide 16 meters into 5 equal sections, then find the total length of 8 of those sections.
3. Add 5 meters 8 times because multiplying by a fraction is repeated addition.
4. Divide 16 meters by $\frac{5}{8}$ because multiplying by $\frac{5}{8}$ is the same as dividing by $\frac{5}{8}$.

Question 8

1. It is the amount of juice in 1 of 2 equal parts when 10 liters is split into 2 equal parts. (correct answer)
2. It is the amount of juice after adding 1 liter 2 times.
3. It is the amount of juice when 10 liters is split into 1 equal part because the numerator is 1.
4. It is the amount of juice in $10\div\frac{1}{2}$ because multiplying by $\frac{1}{2}$ is the same as dividing by $\frac{1}{2}$.

Question 9

1. It represents the number of minutes in 7 of 10 equal parts when 30 minutes is divided into 10 equal parts. (correct answer)
2. It represents 30 minutes divided into 7 equal parts because the numerator is 7.
3. It represents adding $\frac{7}{10}$ minute 30 times.
4. It represents $30\div\frac{7}{10}$ because multiplying by a fraction is the same as dividing by the fraction.

Question 10

1. It is 12 minutes, because each fifth is 20 ÷ 5 = 4 minutes and 3 blocks are 3 × 4 = 12 minutes. (correct answer)
2. It is 4 minutes, because you only find one-fifth and stop.
3. It is 23 minutes, because multiplying always increases the time.
4. It is 20 ÷ 3 minutes, because you divide by the numerator instead of the denominator.

Question 11

1. It represents 2 cups, because you take 2 cups from 9 cups.
2. It represents 6 cups, because you divide 9 cups into 3 equal parts (3 cups each) and take 2 parts. (correct answer)
3. It represents 13.5 cups, because multiplying always makes the amount larger.
4. It represents 9 ÷ 2 cups, because you swap the fraction and divide.

Question 12

1. It is 9 meters, because 12 ÷ 4 = 3 meters per part and 3 parts make 9 meters. (correct answer)
2. It is 3 meters, because you only take the numerator and ignore the denominator.
3. It is 16 meters, because multiplying by a fraction always increases the amount.
4. It is 12 ÷ 3 meters, because the numerator tells how many equal parts to divide into.

Question 13

1. It represents 12 cans, because each group is 28 ÷ 7 = 4 cans and 3 groups make 12 cans. (correct answer)
2. It represents 4 cans, because you only find one-seventh and stop.
3. It represents 35 cans, because multiplication makes the number of cans larger.
4. It represents 28 ÷ 3 cans, because you divide by the numerator.

Question 14

1. It means each group has 24 ÷ 6 muffins, and you take 5 groups.
2. It means you are taking less than all 24 muffins, so the answer should be less than 24.
3. It means you should divide 24 muffins into 5 equal groups, because the numerator tells the number of groups. (correct answer)
4. It means you can find one-sixth of 24 muffins first, then count five of those sixths.

Question 15

1. It represents 3 liters of water because you divide 12 by 4 and then use 1 part.
2. It represents 16 liters of water because multiplying always makes the amount bigger.
3. It represents 9 liters of water because 12 is divided into 4 equal parts and you take 3 of those parts. (correct answer)
4. It represents 4 liters of water because $12 \div \frac{3}{4}=4$.

Question 16

1. Add 18 cups five times because multiplying by a fraction always means repeated addition.
2. Ignore the 6 and take 5 cups because the numerator tells the answer.
3. Divide 18 cups into 6 equal parts, then take 5 of those parts. (correct answer)
4. Divide 18 by $\frac{5}{6}$ because fraction times whole means whole divided by the fraction.
