Question

A recipe that makes 4 servings calls for 2/3 cup of flour. Isadora uses a large container of flour to make 20 servings of the recipe. What number represents the change in the amount of flour from the large container?

Answer 1

2/3 x 5 = 3
the ratio from 4 to 20 is 5, then you multiply it by the original amount
so it's 3
