Roger wants to carpet a rectangular room with the length of 8 ¾ feet and a width of 9 1/3 feet. If he has 85 square feet of carpet, how many square feet of carpet will be left after he covers the floor of the room?

1 answer

8 3/4 = 35/4
9 1/3 = 28/3

35/4 * 28/3 = 980/12 = 245/3

85 = 255/3

so, 255/3 - 245/3 = 10/3
