Question

A sprinkler system is designed to water 5/8 acre of land in 1/4 hour. How many acres of land can it water in 1 hour?

Answer 1

5/8 acre of land ... 1/4 hour
x acres of land = ? ... 1 hour

If you would like to know how many acres of land can the sprinkler system water in 1 hour, you can calculate this using the following steps:

5/8 * 1 = 1/4 * x
5/8 = 1/4 * x       /*4
x = 5/8 * 4
x = 5/2 = 2.5 = 2 1/2 acres of land

The correct result would be 2 1/2 acres of land.
