How it works
Cut the amount into pieces the size of the scoop. Count them, and any part of one.
1/4 cup of rice with a 1/12-cup scoop: how many scoops?
That is 1/4 ÷ 1/12 = 1/4 × 12 = 3.
Example 1: A whole number of scoops
- Mia has 1/4 cup of rice and a scoop of 1/12 cup.
- 1/4 = 3/12, so 3 scoops fit.
- The answer is 3.
Example 2: A part of a scoop
- Mia has 5/8 cup and a 1/6-cup scoop.
- 5/8 ÷ 1/6 = 5/8 × 6 = 30/8 = 3 3/4.
- 3 and a part of a scoop.
Example 3: Another
- Mia has 5/8 cup and a 1/4-cup scoop.
- 5/8 × 4 = 20/8 = 2 1/2.
- 2 and a half scoops.
