Question

A 2 1/2 pound bag of grass seed cover 1/8 of an acre. How much grass seed is needed for 1 acre?

Answer 1

20 pounds of grass seed is needed for one acre.

Explanation:

You can set up a proportion to solve:

`(2.5 pounds)/(1/8 acre)` =
`(x pounds)/(1 acre)`

Cross multiply:

`(1)/(8)`x = 2.5

Divide both sides by
`(1)/(8)` or multiply both sides by 8.

x = 20

Answer 2

8 times more 8*2 1/2 = 20 pounds.
