There are 2 cups in a pint, therefore to find the number of cups in 20 pints you would multiply 20 pints by 2.
20 pints = 40 cups (20 * 2)
There are 4 quarts in a gallon, so to find the number of <em>gallons </em>there are in 29 quarts you would divide 29 quarts by 4.
29 quarts = 7.25 gallons (29/4)
