rectangles P, Q, R, and S are scaled copies of one another. For rach pair, decide if the scale factor from one to the other is greater than 1, equal to 1, or less than 1.

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
