The Problem

You are interested in purchasing a wide-screen television set at Target. On this type of TV, the ratio of screen width to screen height is 16 to 9. If a certain model you are considering has a screen width of 48 inches, what is the height of the screen

Answer provided by our tutors

height = x

width = y

=> 16/9 = y/x

16x = 9y  => x = 9y/16 (1)

y = 48 (2)

from (1), (2)

=> x = 9*48/16 = 27

=> height = 27 in
