On a Saturday, Saul can cut 4 lawns in 6 hours. If Mitch can mow lawns at the same rate, how long will it take him to mow 9 lawns?

A way to solve this is to write a proportion and equation.

Step one, the proportion: # of lawns / hours 4/6 = x/9

x = number of lawns Mitch can mow.

Step two, the equation: 4/6 = x/9

-Cross multply

- you'll get, 6x and 36

- divide six from 6x and 36 to get the variable by itself (1x or x, and 6.)

- you'll now be left with, x = 6

Your answer is 6 lawns!

Mitch and mow 6 lawns in 9 hours!
