There are two gallons in eight quarts. It takes 4 quarts (from the word for "four) to make one gallon. (Eight quarts) x (one gallon/four quarts)= two gallons.
8 quarts is 2 gallons. i know this because there are 4 quarts in one galoon so there are 8 quarts in 2 galoons. You take the number of quarts and divide it by 4.
