Question

A construction company is setting up signs on 5 miles of road. If the company places one sign every 1/3 mile, how many signs will it use?

Answer 1

75

Explanation:

1) Divide 5 by 1/3.

Use the rule --->
`a/(b)/(c) =a*(c)/(b) .`

5 * 3

15

Due to this being a proportional equation, you multiply 15 by 5.

5:(1/3)=75
