Question

a recipe which yields 5 serving calls for 2 cups of milk. how many cups of milk are needed to make 9 servings?

Answer 1

3.6 cups of milk

Explanation:

Create a proportion where x is the number of cups of milk needed for 9 servings:

`(5)/(2)` =
`(9)/(x)`

Cross multiply and solve for x:

5x = 18

x = 3.6

So, 3.6 cups of milk are needed to make 9 servings.
