The length of a rectangle is 7 1/2 inches and the width is 4 3/4 inches. What is the ratio, using whole numbers, of the length t

Mariana [72]

Ratio is a division in its simplest form.
To get the ratio of length to width, divide the two then simplify.

In this case, convert the length and width into decimals.

length = 7 1/2 = 7.5
width 4 3/4 = 4.75

ratio of length to width is;
7.5/4.75 = 750/475

This can now be written as;
750 : 475
Dividing both sides by 25;

= 750/25: 475/25

= 30 : 19
