Final answer:

Barbara will use a total of 30 square tiles to cover her craft room floor, where 18 tiles are red, comprising 6/10 of the total.

Step-by-step explanation:

The student is asking about tiling a floor and wishes to know how many square tiles are needed in total if 6/10 of the tiles are red and she has used 18 red tiles.

To solve this, we use a proportion where 6/10 (the proportion of red tiles) is equivalent to 18 (the number of red tiles) over the total number of tiles (x).

Create an equation from the proportion:

\(\frac{6}{10} = \frac{18}{x}\)

Solve for x by cross-multiplying:

\(6 \cdot x = 18 \cdot 10\)

\(6x = 180\)

\(x = \frac{180}{6}\)

\(x = 30\)

So, Barbara will use a total of 30 square tiles to cover her craft room floor.
