First, find the number of cups in 64 fluid ounces.
Since 8 fluid ounces = 1 cup, divide 64 by 8.
64 ÷ 8 = 8
So, 64 fluid ounces = 8 cups. Next, find the number of pints in
8 cups.
Since 2 cups = 1 pint, divide 8 by 2.
8 ÷ 2 = 4
So, 64 fluid ounces = 4 pints.

since 8 fluid ounces = 1 cup
and 2 cups = 1 pint, you
need to divide twice.
64 ÷ 8 = 8 and
