Question

Sam is using a repeating pattern. The rule is "Blue Tile, White Tile, Black Tile." If he uses 85 tiles, how many will be black?

Answer 1

the answer is 42 times because he uses blue before black so you just needs to divide two by 85 which gives you 42.5 but 42 is the answer because when you reach 85 he will use blue tile so 42 is the answer so the answer is half of 42
