Question
The kitchen floor of your home 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.
2. Express the area of each tile in square feet.
3. How many tiles are required to tile the floor?
4. Explain how your answer relates to the real world  

Answer
Hello Chasity


Problem #1

We are required to find the area of the floor.

First let’s put the length and the width in a suitable format.

Width = 12’ 6’’ means 12.5 ft or 25/2 because 6 inch means 0.5 foot
Length = 10’4’’ means 10 ⅓ or 31/3 because 4 inch is one third of a foot.

Area = 25/2 * 31/3 = 775/6 square feet

Problem #2

The tiles are squares and 5 inches or 5/12 feet long and wide. So their area is
Area = 5/12 * 5/12 = 25/144 square feet.

Problem #3

You have to divide the area of he floor by the area of the tiles

X = (775/6)/ (25/144) = 744 Tiles are needed

I love mathematics as it is the mother of all sciences. I had an outstanding math results while I was in school. The tradition continues while I am in university. I have been helping elementary school Students for the past five years with mathematics problems. In fact, I have a brother who is four years younger than me I usually help him to understand what the crux of the question is before trying to solve it. He loves math very much, he is indeed one of the top scorers form his class in Mathematics. I didn’t stop helping my younger relatives after I joined the Engineering campus and I am more than ready to help anyone with my skill.
