1. Write 12 cookies to 30
brownies as a ratio in
simplest form.
5:2
12:18
2:5

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.

If i'm correct the answer is $15.97
