Aurelio is purchasing carpet tiles to cover an area of his living room floor that is $8\dfrac{1}{3}$ feet wide by $10$ feet long. Each carpet tile is a square $20$ inches wide by $20$ inches long. What is the minimum number of carpet tiles that Aurelio must purchase to cover this area of his living room floor?

Start by converting the width and length to inches.

$$w= 8\frac{1}{3} \text{ ft } = 100 \text{ in}$$ $$l = 10 \text{ ft} = 120 \text{ in}$$

Since each tile is 20 by 20, we will need 5 by 6 tiles = 30 tiles
