Jamaal bedroom has an area of 120 square feet. The width of the room is 5/6 the length of the room. What are the dimensions of the room.

(1) Answers

The area of the room is 120 sf. The easiest guess is that the room is 10'x12' because 10x12 equals 120. To test whether this guess fits the criterion of 5/6, reduce 10/12 by dividing by 2/2, which equals 5/6, so the room IS 10'x12'
