Sam is tiling 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? Enter your answer in the box
To find the number of black tiles, we need to determine the number of times the pattern is repeated in 85 tiles and then multiply that by the number of black tiles in one pattern.
The pattern consists of three tiles: blue, white, and black. Among these three tiles, one is black.
If the pattern is repeated n times, the number of black tiles will be n.
To find the number of times the pattern is repeated in 85 tiles, we divide 85 by 3 (the number of tiles in the pattern):
85/3 = 28.3333...
Since we cannot have a fraction of a repetition, we round down to the nearest whole number.
The pattern is repeated 28 times in 85 tiles.
Therefore, the number of black tiles is 28.
Answer: <<28>>28
