If you want to know the number of whole tiles, then
11.5/1.2 = 9.6
9.5/1.2 = 7.9
So, assuming the cut pieces are not used, you will need
10x8 = 80 tiles
a kitchen is shaped like a rectangle with dimensions of 11 1/2 ft. by 9 1/2 ft. the floor of the room is made of square tiles with a side length of 1.2 ft. What is the number of tiles that will cover the kitchen floor?

437 tiles
how did you get 437
Test
Sorry about that.
yeeeeet
it's 437 because...
1. change(simplify) 11 1/2 and 9 1/2
23/2(11 1/2) and 19/2(9 1/2) because 11x2+1=23 and 9x2+1= 19
2. multiply straight across.
23/2 x 19/2 = 437(23 x 19)/4(2x2)
3. Divide it by the area of a square tile
area of square tile= 1/4 because... area= length x height and square tile mean a tile that has an equal size of length and height.
so 1/2x 1/2= 1/4
now divide 437/4 by 1/4, which is 437.
because... when you divide, you flip the fraction in the back and change the divide symbol to multiply, so it will look like 437/4 x 4/1(simplify to 4)=1748/4 = 437
so the answer is 437, but try to not cheat while the test and use my answer on test CORRECTIONS
