A tile is 38 cm long and the space between the tiles is 0.8. How many tiles are required to build a floor 5.82 m long?
5.82 m = 582 cm
N * ( 38 + 0.8 ) = 582
N * 38.8 = 582 Divide both sides with 38.8
N = 582 / 38.8
N = 15 tiles
N * ( 38 + 0.8 ) = 582
N * 38.8 = 582 Divide both sides with 38.8
N = 582 / 38.8
N = 15 tiles
