Question

Tom's kitchen is 12.5 feet wide. He wants to tile the floor with 0.75-foot-wide tiles. How many tiles will be needed for one row of tiles that extend across the length on the floor?

Answer 1

He will need 17 tiles to go across one row of his kitchen floor.

. 75 x 17 = 12.75

using 17 tiles exceeds the length by a little bit, however if we were to use one less tile (16 x .75 = 12) the tiles wouldn't be long enough to cover the length of 12.5 feet.
