You can put this solution on YOUR website! the kitchen floor is 12'6" in width and 10'4" in length. you have decided to put in a new tile floor. the tiles that you have selected are 5" on each side.
1. express the area of the kitchen floor, in square feet, as an improper fraction.
Ans: (12 1/2)(10 1/3) = 120 + 4 + 5 + 1/6 = 129 1/6 sq. ft.
-----------------------------------------------------------
2. express the area of each tile in square feet.
Ans: 5" x 5" = (5/12)(5/12) = 25/144 sq. ft.
-----------------------------------------------------------
3. how many tiles are required to tile the* floor?
Ans: [129 1/6]/[25/144] = (775/6)/(25/144) = (775/25)*(144/6)
= 31*24 = 744 tiles
