If it takes 7.1 pounds of seed to plant one acre of grass, how many acres can be planted with 9.94 pounds of seed?

Answer 1

Knowing the ratio of seeds to acre (1 acre : 7.1 lb), we can multiply our final amount of seeds to get the total acres.

= 9.94 lb x (1 acre / 7.1lb)

= (9.94 lb x 1 acre) / 7.1lb

= 1.4 acres

By orienting our fraction such that the units cancel, we get our answer in number of acres to be 1.4 acres.

Hope this helps!
