Answer 1

30square tiles will be used to cover the floor

Explanation:

Given:

Number of tiles to be red = 6/10

Total number of tiles used =18

To Find:

how many square tiles will be used to cover the floor = ?

Solution:

Let the number of square tile used to cover the floor be x

Then

`x * (6)/(10) =18`

`x =(18)/((6)/(10))`

`x = (18 * 10)/(6)`

`x = (180)/(6)`

x = 30
