Answer 1

Hello.

He owns 1,600 acres.

Divide 1,600 by 4 and you get 640s. The answer we need.

Hope it helps :)

Answer 2

This would be a question that would involve division. 

We do: (1,600 ÷ 4) and therefore, this would give us $a= 640s$ just as we were looking for, and therefore, B would be your correct answer.
