Question

How many cups of whole wheat flour does it take to make 30 biscuits if it takes 2 cups of whole wheat flour to make 8 biscuits

Answer 1

30/8 = 15/4... 15/4 x 2 = 7.5
The answer is 7.5

Answer 2

2/8 = x / 30...2 cups to 8 biscuits = x cups to 30 biscuits
cross multiply
(8)(x) = (30)(2)
8x = 60
x = 60/8
x = 7.5 (or 7 1/2) cups <==
