Question

A scale model of a house is 1 ft. long. The actual house is 50 ft long. In the model, the window is 1 1/5 in. high. How many feet high is the actual window?

Answer 1

first, identify the ratio:
1:50 (1 foot on the model is 50 feet on the house)
to find the actual height of the window multiply 1 1/5 by 50
$\frac{6}{5}$*$\frac{50}{1}$=$\frac{300}{5}$
300/5 simplifies into 60
the height of the real window is 60 feet
