Hank wants to add a row of tile to his kitchen wall. The space is 5.75 feet long. He plans to put a \frac {3}{4} 4 3 –foot yellow tile in the center. He'll fill the rest of the space with blue tiles that are 3 inches long. How many 3-inch blue tiles will he need?

He will need 20 3-inch blue tiles

Step-by-step explanation:

Here, the total space to fill is a length of 5.75 ft

The tiles to place at the center has 3/4 ft which is same as 0.75 ft

The length left unfilled will be 5.75 - 0.75 = 5 ft

Now we want to know the number of 3 ft tiles needed to fill up this length;

Mathematically, we know that

1 ft = 12 inches

So 5 ft will be 5 * 12 = 60 inches

So the number of 3 inch tiles needed to fill this length will be 60/3 = 20 tiles
