My name is Virjeannia and my I am trying to help my son with his algebra homework, he is in the 6th grade.

What is the ratio of 3 cups to 3 quarts?

Virjeannia,

I am going to assume that you are talking about US quarts which contain 32 ounces. One cup is 8 ounces and hence 1 quart is 32/8 = 4 cups. Thus 3 quarts is
3  4 = 12 cups. Thus 3 cups to 3 quarts is in the ratio

3:12 which is 1:4
