Dalia is installing a tile floor in a rectangular room. Dalia has 152 tiles available to tile the room. If each row requires 9.5 tiles, and 19 tiles broke while Dalia is laying the floor, how many full rows of unbroken tile can she install before running out of tiles?
Q. Dalia is installing a tile floor in a rectangular room. Dalia has 152 tiles available to tile the room. If each row requires 9.5 tiles, and 19 tiles broke while Dalia is laying the floor, how many full rows of unbroken tile can she install before running out of tiles?
Calculate Remaining Tiles: First, we need to determine the total number of tiles Dalia has left after accounting for the broken tiles. Dalia started with 152 tiles and 19 broke.Calculation: 152 tiles - 19 broken tiles = 133 tiles remaining.
Determine Tiles per Row: Next, we need to figure out how many tiles are needed for one full row. According to the problem, each row requires 9.5 tiles.
Calculate Full Rows: Now, we divide the total number of unbroken tiles by the number of tiles required for one row to find out how many full rows can be installed.Calculation: 133 tiles ÷9.5 tiles/row =14 rows.
Check for Whole Number: However, we need to check if the result is a whole number since we can only install full rows. In this case, 14 is a whole number, so Dalia can install 14 full rows of unbroken tiles.
