Answer
48,000 oz
Work Step by Step
1 $\frac{1}{2}$ tons = oz.
Use the unit fraction $\frac{2000 pounds}{1 ton}$ to change ton to pounds and the unit fraction $\frac{16 ounces}{1 pound}$ to change pound to ounces. Notice how all the units divide out except ounce, which is the unit you want in the answer.
3/2 ton *$\frac{2000 pounds}{1 ton}$ * $\frac{16 ounces}{1 pound}$ = 48,000 oz
