Question

On a map. 1 inch represents 3 miles. How many miles long is a road that is 2 1/2 inches long on the map?

​

Answer 1

7 1/2

Explanation:

1=3

Turn the 2 1/2 to a decimal which is now 2.5

2.5=x

Find x by multiplying 2.5 and 3

2.5*3=7.5

Turn 7.5 back into a fraction

7.5=7 1/2

Answer 2

15/2

Explanation:

2 1/2 = 5/2

x/(5/2) = 3/1

x = (5/2)3/1

x = 15/2
