To find the number of tiles in one square foot, we need to divide the total number of tiles by the total area in square feet.
We're given that there are 15 1/2 tiles in an area of 2 1/5 square feet.
First, let's convert 15 1/2 to an improper fraction:
15 1/2 = (2 * 15) + 1 = 30 + 1 = 31/2
Next, let's convert 2 1/5 to an improper fraction:
2 1/5 = (5 * 2) + 1 = 10 + 1 = 11/5
Now, we can divide the number of tiles by the total area:
(31/2) รท (11/5) = (31/2) * (5/11) = (31 * 5) / (2 * 11) = 155/22
Therefore, there are 155/22 tiles in one square foot.
