Question

williams only has 1 3/4cups of flour ,so he only make 2/3 0f a batch of biscuits. how much flour is needed for a full batch of biscuits?

Answer 1

2 5/8 cups of flour

Explanation:

Use a proportion.

1 3/4 cups of flour is to 2/3 of a batch as x cups of flour is to 1 batch.

1 3/4 : 2/3 = x : 1

2/3 x = 1 3/4 * 1

2/3 x = 1 3/4

2/3 x = 7/4

3/2 * 2/3 x = 3/2 * 7/4

x = 21/8

x = 2 5/8

Answer: 2 5/8 cups of flour
