4. You need $2$ cups of sugar for one mini-batch. (correct answer)

Question 2

1. First split the whole tray into 3 equal parts, then split one of those parts into 4 equal pieces. (correct answer)
2. First split the whole tray into 4 equal parts, then take 3 of those parts.

2. $\tfrac{1}{18}$ of a pizza (correct answer)
3. $\tfrac{1}{3}$ of a pizza
4. $\tfrac{1}{9}$ of a pizza

Question 5

1. $\tfrac{3}{4}$ cup
2. $\tfrac{1}{12}$ cup (correct answer)
3. $\tfrac{1}{7}$ cup
4. $\tfrac{1}{3}$ cup

Question 6

1. $\tfrac{1}{2}$ of a pan
2. $\tfrac{1}{8}$ of a pan (correct answer)
3. $\tfrac{1}{2}$ of $\tfrac{1}{4}$ of a pan
4. $\tfrac{1}{4}$ of a pan

Question 7

1. Each small cup gets $\tfrac{1}{9}$ cup of juice. (correct answer)
2. Each small cup gets $1$ full cup of juice.
3. Each small cup gets $\tfrac{1}{6}$ cup of juice because you divide only the denominator.
4. Each small cup gets $\tfrac{1}{3}$ cup of juice because the amount does not change when you share it.

Question 8

1. Split the whole loaf into 6 equal parts; one part is the amount for each sandwich. (correct answer)
2. Split the whole loaf into 3 equal parts; two parts are the amount for each sandwich.
3. Split the whole loaf into 2 equal parts; one part is the amount for each sandwich.
4. Split the whole loaf into 3 equal parts; one part is the amount for each sandwich.

Question 9

1. $\frac{1}{56}$ because the denominator doubles each time when dividing by 2 (correct answer)
2. $\frac{1}{30}$ because you add 2 to the denominator when dividing by 2
3. $\frac{2}{28}$ because dividing by 2 means multiplying the numerator by 2
4. $\frac{1}{14}$ because division and multiplication by 2 are inverse operations

Question 10

1. Compare $\frac{1}{40}$ to $\frac{1}{8}$ and verify that $\frac{1}{40}$ is smaller, which makes sense
2. Multiply $\frac{1}{40} \times 5 = \frac{5}{40} = \frac{1}{8}$ to confirm it equals her starting amount (correct answer)
3. Add $\frac{1}{40} + 5 = \frac{1}{40} + \frac{200}{40} = \frac{201}{40}$ and check if this is reasonable
4. Divide $\frac{1}{40}$ by 5 again to get $\frac{1}{200}$ and see if this seems like enough clay

Question 11

1. $\tfrac{1}{4} \div 4$ is larger than $\tfrac{1}{4} \div 2$ because more kids means more cake per kid.
2. $\tfrac{1}{4} \div 2$ and $\tfrac{1}{4} \div 4$ are equal because the starting fraction is the same.
3. $\tfrac{1}{4} \div 4$ is smaller than $\tfrac{1}{4} \div 2$ because the same $\tfrac{1}{4}$ is split into more equal parts. (correct answer)
4. $\tfrac{1}{4} \div 4$ is larger than $\tfrac{1}{4}$ because division makes numbers bigger.

Question 12

1. Each length is smaller than $\tfrac{1}{5}$ of the rope.
2. Each length is $\tfrac{1}{10}$ of the rope.
3. The $\tfrac{1}{5}$ piece is partitioned into 2 equal parts.
4. Each length is $\tfrac{1}{3}$ of the rope. (correct answer)

Question 13

1. Each person gets $\tfrac{1}{8}$ of the whole pizza.
2. The result must be smaller than $\tfrac{1}{4}$ because the $\tfrac{1}{4}$ is being split.
3. The answer is $\tfrac{1}{2}$ of the whole pizza. (correct answer)
4. The $\tfrac{1}{4}$ piece is partitioned into 2 equal parts.

Question 14

1. $\tfrac{1}{6}$ of a sandwich (correct answer)
2. $\tfrac{3}{2}$ of a sandwich
3. $\tfrac{1}{2}$ of a sandwich
4. $\tfrac{1}{1}$ of a sandwich

Question 15

1. Sharing among 4 students gives a larger piece to each student than sharing among 2 students.
2. Sharing among 4 students gives each student $\tfrac{1}{8}$ yard, which is smaller than $\tfrac{1}{4}$ yard from sharing among 2 students. (correct answer)
3. Sharing among 2 students gives each student $\tfrac{1}{2}$ yard, and sharing among 4 students gives each student $\tfrac{1}{2}$ yard.
4. Sharing among 4 students gives each student $\tfrac{4}{2}$ yards because you divide by 4.

Question 16

1. Each student gets $\tfrac{3}{2}$ of a pitcher.
2. Each student gets $\tfrac{1}{5}$ of a pitcher.
3. Each student gets $\tfrac{1}{6}$ of a pitcher. (correct answer)
4. Each student gets $\tfrac{1}{2}$ of a pitcher.

3. $\tfrac{1}{7}$ meter
4. $\tfrac{1}{3}$ meter

Question 19

1. Each container gets $\tfrac{1}{4}$ liter because half a liter split into 2 equal parts makes fourths. (correct answer)
2. Each container gets $1$ liter because dividing by 2 doubles the amount.
3. Each container gets $\tfrac{1}{2}$ liter because the amount stays the same when you share it.
