Question
Lucy adding a row of square tiles across the top of a mirror. Each tile is 4.5 cm wide. The mirror is 56 cm wide. Lucy wants to tile right across the top, with no gaps between the tiles. What calculation should she do to work out how many tiles she needs.
Answers
GPT 3.5
Lucy should divide the width of the mirror by the width of each tile to calculate the number of tiles she needs.
56 cm รท 4.5 cm = 12.44
Since Lucy cannot have a fraction of a tile, she should round up to the nearest whole number. Therefore, Lucy needs 13 tiles to cover the top of the mirror with no gaps.
