Tia is painting her house. She paints 34 1/2 square feet in 3/4 hour. At this rate how many square feet can she paint each hour.

46 square feet per hour

If you want an explanation of how the answer is 46 sq ft/hr, all you have to do is divide 34.5 by the three of the 3/4 and you'll get 11.5. That is the amount of square feet she can paint in a fourth of an hour. Now, multiply this by four, and you get 46 sq. ft.
