Answer 2

The ratio is 2 1/2 : 5

Multiply both sides by 8 / 5

The new ratio is (8/5) x 2 1/2 : 8

Simplify to get 4 : 8

A simpler way to solve is to recognize the ratio as 1 : 2 (2 1/2 is half of five)

Then you get that the cups of milk needed is the same as the servings divided by two

8/2 = 4
