Use a rectangular tile that is 8 decimeters long and 6 decimeters wide to pave the floor. To pave a square, how many decimeters is the side length of the square at least? How many tiles were used?

Use a rectangular tile that is 8 decimeters long and 6 decimeters wide to pave the floor. To pave a square, how many decimeters is the side length of the square at least? How many tiles were used?

The least common multiple of 8 and 6 is 24
So the side length is at least 24 decimeters
It takes 24 * 24 (6 * 8) = 12 pieces
