#### Work Step by Step

$6750 \div 62 \frac{1}{2}$ is the number of apartment units that can be carpeted.
Estimate: Use front end rounding then.
$7000 \div 60 =116.\overline6$
Drop the fractional part of the answer since only whole apartment units would be carpeted.
Exact Convert mixed numbers to improper fractions.
$\frac{6750}{1} \div \frac{125}{2}$ Multiply by the reciprocal of the divisor.
$\frac{6750}{1} \times \frac{2}{125}$ Eliminate common factors and multiply.
$\frac{/\!\!\!\!125\times54}{1} \times \frac{2}{/\!\!\!\!125}$ = $\frac{108}{1}$
