Leah's house has media room with a large flat screen tv. The media room tv has a width of 8 feet and a height of 4.5 feet. The flat screen in the living room has a height of 27 inches and has the same width to height ratio as the media room tv. What is the width of the living room tv?

Respuesta :

the ratio of the media room tv's width to height is 8ft to 4.5ft or 8/4.5

since the ratio of the living room tv's width to height is the same, the ratio would be
x/27 = 8/4.5
with x being the living room tv's width. Solve for x
x = (8/4.5)(27)
   = 48
The width of the living room tv is 48 inches
width     8ft               x   in
                       =
height   4.5ft           27 in

27x8
 4.5

x = 48 in.
