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

We first need to convert 2.25 miles into yards. Thus, we need to do a unit conversion in this problem. There are 1760 yards in a mile. Thus, we obtain: $\frac{2.25 miles}{1} \times \frac{1760 yards}{mile} =3960$ yards. Note, we need to cancel out the unit of miles, so we multiply 2.25 miles by a fraction with miles in the denominator.
