A recipe for a large of cookies calls for 3 1/4 cup of flour. Amos wants to make half of a batch of cookies. How much flour should he use
3 1/4 = 2 5/4
so half of that is 1 5/8
or,
1/2 * 3 1/4 = 1/2 * 13/4 = 13/8 = 1 5/8
Amos should use 1 5/8 cups of flour.
How do you know that?
To determine how much flour Amos should use for half of a batch of cookies, we need to divide the original amount of flour called for in the recipe by 2.
The original amount of flour is 3 1/4 cups. To divide this by 2, we can follow these steps:
1. Convert the mixed number 3 1/4 to an improper fraction:
3 1/4 = (4 * 3 + 1) / 4 = 13/4
2. Divide the result by 2:
13/4 ÷ 2 = 13/4 * 1/2 = 13/8
So, Amos should use 13/8 cups of flour for half of a batch of cookies.
