Question

The ratio of the length of a rectangle to its width is 4 1/2 : 2 1/4. What is the unit rate of the length per width of the rectangle?

Answer 1

Answer:  

The ratio simplifies fully to 2:1

=======================================================

Work Shown:

4 & 1/2 = 4 + 1/2 = 4 + 0.5 = 4.5

2 & 1/4 = 2 + 1/4 = 2 + 0.25 = 2.25

The original ratio is the same as 4.5 : 2.25

Divide both parts by 2.25 and you'll end up with 2:1

4.5/2.25 = 2

2.25/2.25 = 1

This means the length is twice as long compared to the width.
