Question

a waffle recipe uses 3 cups of mix for 4 waffles. How much mix would you need to make 12 waffles

Answer 1

Since we know that 3 cups make 4 waffles, and we want 12 total waffles, we know that we need to multiply the recipe by 3 in order to have enough ingredients for 12 waffles.

So we multiply 3 cups by 3 (because we need to triple the recipe) and we get:

$3*3=9$

So we need 9 cups of mix to make 12 waffles.
