12 ounces                        x
--------------- = ----------------
10 pounds of soil      120 pounds of soil

Set the equation up as a proportion and solve for x:
10x = 1440
----    -----
10          10
x = 144 ounces
The question asks for the answer in pounds, and 16 ounces = 1 pound.
144/16 = 9
