Question

the ratio of the width of a rectangle to its length is 5:8 what is the width in feet if the length is 12 feet

Answer 1

Explanation:

Set this up as a proportion, with width on the top of the ratio and length on the bottom and fill in according to the info you've been given:

`(w)/(l):(5)/(8)=(x)/(12)`

x is the unknown width we are looking for. Cross multiply to get

8x = 60 so

x = 7.5
