Question

to make his favorite punch Mr. Batalas uses 2/3 cup of ginger ale and 1/4 cup of cola to make 1 cup of punch. How many cups of each are required to make 20 cups of punch?

Answer 1

I'm going to assume that the question means to say glasses of punch instead of cups because those amounts would not add up to one cup.

To make his favorite punch Mr. Batalas uses 2/3 cup of ginger ale

and 1/4 cup of cola to make 1 glass of punch.

How many cups of each are required to make 20 glasses of punch?

We simply take each fraction times 20.

2/3 * 20 = 13 1/3 cups of ginger ale

1/4 * 20 = 5 cups of cola
