======================================
Work Shown:
4 cups = 1 quart .... given info
4*(4 cups) = 4*(1 quart) ... multiply both sides by 4
16 cups = 4 quarts
4 quarts = 1 gallon .... given info
16 cups = 1 gallon .... replace "4 quarts" with "16 cups"
3*(16 cups) = 3*(1 gallon) ... multiply both sides by 3
48 cups = 3 gallons
