There are various ways to do this problem.  You could find a scale factor with units in/ft, ft/ft or in/in.

In any case, please write the identity (36 in) / (24 ft) and reduce that as much as possible.   If you wish, convert this to in / in or ft / ft.

Your scale factor has to include units of measurement; your response has none of those.  I've given you three possibilities for units to include in your scale factor.  Choose one and then convert the units of measurement as appropriate.

When you're done, check your scale factor.  You should obtain "24 feet" if you multiply "36 inches" by your scale factor.
