Question

A recipe asks for 2/3 cup of milk. How many cups of milk are needed for 1 1/2 recipes?

Answer 1

In order to solve this problem, we need to multiply 2/3 * 1 1/2.

$\frac{2}{3} *1 \frac{1}{2} =6/6=1$

So, we need 1 cup of milk to make 1 1/2 recipes.

Answer 2

(1 1/2)(2/3)

((1*2+1)/2)(2/3)

(3/2)(2/3)

6/6

1

So one cup of milk is needed to make one and a half times the original recipe.
