Question

Your group has 12 red tiles and 18 blue tiles. Your job is to arrange the tiles in rows. You must use all the tiles, a row can only contain only blue or only red tiles, each row can only contain the same number of tiles, and the rows should be as long as possible.

Solution: Find the GCF for 12 and 18 which is 6. So, the longest row will have 6 tiles; 3 rows of blue and 2 rows of red? Is this correct?
