Afarmer needs to mix 12 ounces of fertilizer for every 10 pounds of soil. how many pounds of fertilizer will the farmer need to make a mix that contains 120 pounds of soil? a) 0.06 b)9 c)144 d)230.4

We can use a ratio to find the answer. Since the final answer is asking for pounds, we can just change all of the units to pounds now.
12 ounces=3/4 pounds

fertilizer : soil
3/4 : 10 = x : 120

90 =10x
9=x

You will need 9 pounds of fertilizer, so the answer is B)9.

Hope this helps!
