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?

Width 8ft x in

=

height 4.5ft 27 in

27x8

4.5

x = 48 in.

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
