Sam is tilling a floor he will use the same repeating pattern for the entire floor the rule is blue tile white tile black tile if he uses 85 tiles how many will be black
To determine how many black tiles Sam will have, we need to find out the number of times the pattern: blue tile, white tile, black tile, repeats.
The pattern consists of 3 tiles: blue, white, and black. Therefore, the pattern repeats itself every 3 tiles.
Since Sam is tiling a floor with 85 tiles, we can divide 85 by 3 to find out how many times the pattern repeats:
85 รท 3 = 28 remainder 1
This means that the pattern repeats 28 times with 1 extra tile left.
Since the pattern consists of blue, white, and black tiles, Sam will have 28 black tiles in total.
