Question

I need to figure out what proportion I need to use to convert 3,600 feet into miles

Answer 1

There are 5280 feet in a mile:

5280ft/mi

When using proportions to solve for unknown quantities, you need to keep the same units on the same side. This means keep "ft" on the top side and "mi" on the bottom side.

I would go with the second choice.

Answer 2

Answer:

0.682 mile

Step-by-step explanation:

You need to know or be able to find the conversion equality

1 mile = 5280 feet.

Then

3600 ft       1 mi

------------ * ------------ = 0.682 mile

      1          5280 ft
