To answer this you will need to know that there are 43,560 square feet in 1 acre.

1. Half of this is 43560/2 or 21780 square feet.

2. Out of this amount Blake has already mowed 3/5 of the lawn. This means he must mow 2/5 (1 - 3/5) more.

2/5 of 21,780 ft.² can be represented this way:

2/5 x 21780 =?

He needs to mow 8712 ft.² more.
