Answer

5000 lb

Work Step by Step

2$\frac{1}{2}$ tons = lb Use a unit fraction with pound (the unit for your answer) in the numerator, and ton (the unit being changed) in the denominator. Because 2000 pounds (lb) = 1 ton, the necessary unit fraction is $\frac{2000 lb}{1 ton}$ Multiply 2$\frac{1}{2}$ tons times the unit fraction. 2$\frac{1}{2}$tons = $\frac{5}{2}$ tons = $\frac{5}{2}$ * $\frac{2000 lb}{1 ton}$ = 5000 lb
