You need 2 cups of orange juice to make 3 quarts of punch. How many cups of orange juice do you need to make 3 gallons of punch?

3 quarts = 3/4 gallon

2/.75 = x/3

To solve for x, multiply both sides by 3, then divide by .75.

45 quarts

To find out how many cups of orange juice are needed to make 3 gallons of punch, we need to establish the conversion between gallons and cups.
