Final answer:
It will take 16 tiles to cover 1 square yard.
Step-by-step explanation:
To find out how many tiles it will take to cover 1 square yard, we need to calculate the area of one tile.
The tiles are 1/4 by 1/4 yard, so the area of one tile is (1/4) * (1/4) = 1/16 square yard.
To cover 1 square yard, we need to divide the total area by the area of one tile:
1 square yard / (1/16 square yard) = 1 * (16/1) = 16 tiles.
