## Algebra 1: Common Core (15th Edition)

We need to do a unit conversion in this problem. There are 12 inches in a foot. Thus, we obtain: $\frac{6.5 feet}{1} \times \frac{12 inches}{foot} =78$ inches. Note, we need to cancel out the unit of feet, so we multiply 6.5 feet by a fraction with feet in the denominator.
