Answer:
Step-by-step explanation:
Use the factor-label method you learned in chemistry (also known as dimensional analysis), keeping in mind 2 things:
the label you want needs to be on the top of the equivalent ratio, and
that there are 5280 feet in 1 mile. Having said that:
![7feet*\frac{1mile}{5280 feet}=](https://tex.z-dn.net/?f=7feet%2A%5Cfrac%7B1mile%7D%7B5280%20feet%7D%3D)
The math tells us to divide 7 by 5280. That means that
7 feet = .0013257576 miles, to however many decimal places you need. That 7575 is repeating, btw.
