Question

Nan and Santo are designing a coffee table using 4 inch tiles. Nan uses 30 tiles and Sato uses half as many how many . how many total tiles did they use? If the area of the table is 36 inches by 24 inches, will they have enough to cover the table?

Answer 1

First, you have to find half of 30. To find "half" means that you have to divide by 2. 30 divided by 2 is 15, because 15 + 15 = 30.
30 + 15 = 45
Salo and Nan used 45 total tiles.
Finally, to find out if they have enough tiles you have to divide 36 and 24 by 4. This is because that will tell you how many 4 inch tiles need to be used. So, 36/4 is 9, and 24/4 is 6.
9 tiles + 6 tiles = 15 tiles
Yes, they will have enough tiles to cover the table.
