Question

A recipe calls for 4 cups of pecans for every 5 cups of walnuts. How many cups of pecans should be added to 8 cups of walnuts?

Answer 1

10 cups of pecans.

Explanation:

The ratio between pecans and walnuts are:
`(4)/(5)`×8

So if we make a smaller batch with 1 cup of walnuts, we will need
`(4)/(5)` cup of pecans.

So for 8 cups of walnuts, we will need
`(4)/(5)` x 8 = 6,4 cups or
`6 (2)/(5)` cups of pecans.

Answer 2

5 walnuts = 4 cups of pecans

8 walnuts = 9 cups of pecans
