Demetria is tiling a square area of her bathroom floor. For every 13 white tiles used, she wants to use 12 gray tiles. Draw a grid , 5 squares by 5 squares, then shade the tiles to show a pattern that would match the ratio of white tiles to gray tiles that Demetria would like to use. Then write a ratio to show the relationship between the number of white tiles and the number of gray tiles
Please help me I am very very confused
How would you figure this out?
The answer is 0.0000000000000000000000000000000000001
To figure this out, you can start by understanding the ratio provided, which states that for every 13 white tiles, Demetria wants to use 12 gray tiles.
To draw a grid that matches this ratio, we can use a 5x5 grid representing the square area of the bathroom floor. Each square in the grid will represent one tile.
To determine the number of white and gray tiles to shade, we can first calculate the total number of tiles in the grid. Since the grid is 5 squares by 5 squares, the total number of tiles will be 5 x 5 = 25 tiles.
Next, we can divide the total number of tiles by the sum of the ratio values. In this case, the sum is 13 + 12 = 25.
To distribute the tiles according to the ratio, we can multiply the ratio values by the total number of tiles and then divide by the sum of the ratio values:
Number of white tiles = (13/25) x 25 = 13
Number of gray tiles = (12/25) x 25 = 12
Now we can draw the grid, shading 13 squares as white tiles and 12 squares as gray tiles, based on the calculated quantities.
The ratio of the number of white tiles to gray tiles can be written as 13:12 or simplified as 13/12.
This process ensures that the shaded tiles represent the desired ratio of white to gray tiles in the bathroom flooring pattern.
