Problema Solution
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 (in inches)
Answer provided by our tutors
let
w = 48 in width of the screen
h = the height of the screen
the ratio of screen width to screen height is 16 to 9
w : h = 16 : 9
h = (9w)/16
h = (9*48)/16
h = 27 in
the height of the screen is 27 inches.
