Question

David uses 1 4 cup of apple juice for every 1 2 cup of carrot juice to make a fruit drink. Enter the number of cups of apple juice David uses for 1 cup of carrot juice.

Answer 1

1/2 cups of apple juice.

Explanation:

The ratio between apple juice to carrot juice is

1/4 : 1/2

By using this ratio we can find the number of cups of apple juice needed for one cup of carrot juice.

since 1 cup is twice the carrot juice in the ratio, we need twice the ratio in the apple juice as well.

1/4 * 2 = 2/4

This can be simplified to 1/2
