Question

If it takes 6.7 lb of seed to plant one acre of grass how many acres can be planted with 8.04 pounds of seed?

Answer 1

This is a proportion problem. 6.7lbs to one acre as 8.04 lbs is to x acres.

x= # lbs of seed to cover 8.04 acres


6.7/1=8.04/x
cross multiply

(6.7*x) =(1*8.04)
6.7x=8.04
divide both sides by 6.7

x= 1.2 pounds needed to cover 8.04 acres

Hope this helps! :)
