Question

A recipe that makes 6 servings calls for 1/2 cup of butter. Nancy modifies the recipe so that it can serve 8

How many cups of butter does Nancy need?

Answer 1

6 servings ... 1/2 cup of butter
8 servings .... x cup of butter
We would like to know what is the value of the x.

6 * x = 8 * 1/2
6 * x = 4 /6
x = 4/6
x = 2/3

Result: Nancy needs 2/3 cup of butter for 8 servings.
