A painter is making a shade of purple paint by mixing 2 cups of red paint for every 12 cups of blue paint. Unfortunately, the painter mixed 16 cups of red paint with 6 cups of blue paint. How can the painter fix the mixture to make the desired shade of purple paint?

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
