Question

Brett made a scale drawing of a rectangular rom in his house. the actual length of the room is 12 4 5 ft. the scale he used to make the drawing was 1 4 inch = 1 foot. what is the length, in inches, of the room on the drawing?

Answer 1

First, you want the answers in inches so you make all the measurements into inches, so multiply them all by 12. (since 12 inches =1 foot)

12*12= 144 inches     4*12= 48 inches    5*12= 60 inches
than multiply all of them by 1/4 OR divide them all by 4 (same thing)
you get... 36 inches        12 inches           15 inches in the drawing
