Question

The width to height ratio of a certain computer monitor is 16 to 9. The monitors height is 13.5 inches. What is the width in inches of the monitor?

Answer 1

The width of computer = 24 inches

Explanation:

Given that:

Ratio of width to height = 16 : 9

Height of monitor = 13.5 inches

Width of monitor = x

This forms a proportional relationship

16 : 9 :: x : 13.5

Product of mean = Product of extreme

9x = 13.5 * 16

9x = 216

Dividing both sides by 9

`(9x)/(9)=(216)/(9)\\x=24`

Hence,

The width of computer = 24 inches
