tiffany will us a total of 63 tiles for her art project she only needs 17 more tiles use mental math to find how many tiles she has already
She has 46 tiles
What is your answer?
46
Yes
To find out how many tiles Tiffany has already used for her art project, we need to subtract the number of tiles she still needs from the total number of tiles she will use.
Total number of tiles for the art project = 63
Number of tiles Tiffany still needs = 17
By subtracting the number of tiles she still needs from the total number of tiles, we can determine how many tiles she has already used:
Total tiles - Tiles still needed = Tiles already used
63 - 17 = 46
Therefore, Tiffany has already used 46 tiles for her art project.
