Answer 18

a recipe uses 3 cups of to make 48 cookies .how much flour is needed to make 72 cookies

Answer 19

To answer this question, we can set up a proportion:

3 cups of flour / 48 cookies = x cups of flour / 72 cookies

We can cross-multiply to solve for x:

3 * 72 = 48 * x

216 = 48x

Divide both sides by 48 to solve for x:

x = 216 / 48

x = 4.5

Therefore, 4.5 cups of flour is needed to make 72 cookies.
