Barbara is tiling her craft room floor with square tiles. She wants 6/10 of the square tiles be red. If she uses 18 red tiles,how many square tiles will be used to cover the floor?
My response is I don't really know so yeah sorry
0.6x = 18
x = 30

To find the total number of square tiles that Barbara will use to cover the floor, we can set up a proportion using the number of red tiles and the desired ratio.
Let's assume the total number of square tiles used is "x".
According to the given information, 6/10 of the square tiles will be red, which means that 6/10 of the total tiles will be red.
So we can set up the proportion as follows:
(6/10) = 18 / x
To solve this proportion, we can cross-multiply:
6x = 10 * 18
Now, divide both sides of the equation by 6 to solve for 'x':
x = (10 * 18) / 6
x = 30
Therefore, Barbara will use 30 square tiles to cover the craft room floor.
