we know that: 1 quart = 4 cups 1 cup = 0.0625 gallons And given is: 2 cups = 9 cups of soup so, 1 cup = 4.5 cups of soup going back to the top and using that equation: 1 quart= 4 cups 1/4 quarts = 1 cup so, 1/4 quarts = 0.0625 gallons to make it 6 quarts: (1/4)x 24 = 24 x 0.0625 6 quarts = 1.5 gallons
