Question 19765
Since you have a scale from the problem, you need to use a proportion to solve it.  You are comparing the actual feet to the inches in the blueprint.  So, your proportion should be set up to look like:  {{{((1/4)/1) = (x/22)}}}.  To solve the proportion, cross multiply and divide:  (22 x 1/4 = 5.5; 5.5 divided by 1 = 5.5).
