Answer

Harrison can serve 64 children with 4 gallons of milk.

Work Step by Step

To solve this problem, we need to convert gallons of milk to cups of milk first. To convert gallons of milk to cups of milk, we need to multiply it by the ratio that converts gallons to cups. The ratio that converts gallons to cups is: $\frac{2\ cups}{1\ pint}$ $\times$ $\frac{2\ pint}{1\ quart}$ $\times$ $\frac{4\ quart}{1\ gallon}$ = $\frac{16\ cups}{1\ gallon}$. So, 4 gallons $\times$ $\frac{16\ cups}{1\ gallon}$ = 64 cups of milk. Harrison has 64 cups of milk and needs to distribute this amount to children. Each child requires 1 cup of milk. Now we proceed: 64 cups of milk $\div$ 1 cup = number of children served 64 $\div$ 1 = 64 Harrison can serve 64 children with 4 gallons of milk.
