May baked 24 cookies with 2 cups of flour how many cups of flour does may need in order to only bake 20

The answer is 1 2/3 cups of flowers.

First, Divide the number of cookies by cups of flower to get unit rate, then from there use that number and let it be divided by the amount you want, for example 20. So, 20 divided by 12 is 1.6666, or 1 2/3

24/2=20/x

Cross multiply

24x=2 (20)

Simplify

24x=40

Divide both sides by 24

x=1 2/3
