One gallon equals how many quarts?

One gallon equals how many quarts?

• A. 3 quarts
• B. 4 quarts
• C. 2 quarts
• D. 5 quarts

Answer: (B)

Understand how gallons relate to quarts. A gallon is made up of four equal parts called quarts, so a quart is one-fourth of a gallon. That means four quarts fill one gallon. You can check with fluid ounces: a quart is 32 fluid ounces, so four quarts equal 128 fluid ounces, which is a full gallon. The other numbers don’t fit because three quarts would be 96 ounces, two quarts 64, and five quarts 160—none of these equal a gallon.
