Answer:
1 mi/5280 ft = 5 mi/x ft
Step-by-step explanation:
1 mi = 5280 ft
This is the first fraction:
1 mi/5280 ft
The second fraction:
5 mi/x ft
If the problem asked specifically for the value of variable x, you would multiply 5 miles by 5280 feet to find it.
The problem only asks for the set up of the proportion though so:
1 mi/5280 ft = 5 mi/x ft
