Question

Jessica gets her favorite shade of purple paint by mixing 1/3

cup of blue paint with 1/2 cup of red paint. How many cups
of blue and red paint does Jessica need to make 20 cups of
her favorite purple paint?

Answer 1

8 cups of blue and 12 cups of red

Explanation:

Combine 1/3 c of blue + 1/2 c of red = 5/6 c of purple.

(5/6)x = 20

x = (6/5)20 = 24

this is applied to each of the above measurements to show that you need 8 c of blue + 12 c of red.
