Question

If the height of the actual dollhouse is 4ft what is the height of the model? 4in = 2.5ft

Answer 1

Well, since the scale is 4in = 2.5 ft, then we can set up the following proportion:

First though, convert the 4ft to inches. That is 4 * 12 = 48" in actual height. Also, 2.5 ft * 12 is 30 inches.

Now set up the proportion:
\[\frac{4 inches}{30 inches} = \frac{x inches}{48 inches}\]

Solving for x will give the height of the model, in inches. Hope that helps, @amrjcr.
