Question

Darron uses a family recipe to make hamburgers. If he plans on using 1 1/3 cups of bread crumbs, about how many pounds of hamburgers does Darron need to use to keep the relationship between bread crumbs and hamburgers proportional?

Bread crumbs (c) 1/4 1/2 3/4
Hamburgers (lb) 1 2 3

Answer 1

1/4 cups = 1lb mince divide both by three
1/12 cups = 1/3lb hamburgers

1 1/3 cups = 12/12 cups + 4/12 cups
= 16/12 cups
=16 * 1/3lb hamburgers

- as 1/12 cups = 1/3lb burger, 16/12 cups = 16/3 lb burgers
