Tameka's mother made fish fries for lunch. She made fish ice cream for dessert. It takes 6 small fish to make 1 1/2 cups of ice cream. How many fish does it take to make 4 cups of ice cream?

Let's set up a proportion and let x equal the number of fish needed for 4 cups of ice cream.

6 / 1.5 = x / 4

Cross multiply:

1.5x = 24
x = 24/1.5
x = 16
