Question

The ratio of a model building's dimensions to the building's actual dimensions is 1/52. If the height of the model is 15 inches, what is the height of the actual building in feet?

Answer 1

Set this up as a proportion with the model stuff on top and actual building stuff on bottom.  $\frac{1}{52} = \frac{15}{x}$.  Cross multiply to get x = 780.  The actual building is 780 inches.  In feet that is 65.
