The correct question is
Brett made a scale drawing of a rectangular room in his house. The actual length of the room is 12 4/5 ft. The scale used to make the drawing was 1/4 in.=1 ft. What is the length, in inches, of the room on the drawing?

we know that
scale=measure in the drawing/measure in the actual
measure in the drawing=measure in the actual*scale

in this problem
scale=1/4 in/ 1 ft> 1/4
measure in the actual=12 4/5 ft> (12*5+4)/5> 64/5 ft
so
measure in the drawing=(64/5)*(1/4)> 3.2 in

the answer is
the length, in inches, of the room on the drawing is 3.2
