Answer:

30square tiles will be used to cover the floor

Step-by-step 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

$x \times \frac{6}{10} =18$

$x =\frac{18}{\frac{6}{10}}$

$x = \frac{18 \times 10}{6}$

$x = \frac{180}{6}$

x = 30
