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 inc
1 answer:
Answer:
The width of computer = 24 inches
Step-by-step 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
Hence,
The width of computer = 24 inches
