Laura wants to make a cake. Each cake calls for 2 cups of milk for every 3 eggs used. If Laura wants to make 13 cakes, how much milk and how many eggs will she need?
the ratio is 1 cake needs 2:3. if she wants to make 13 the ratio goes up by a scale factor of 13x so it’s going to be 2x13 and 3x13. that will be 26 cups of milk and 39 eggs
