The ratio of boys to girls at Jackie Chan high school is 5:3. If there are a total of 250 boys in the school how many girls are in the school?

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.

The answer is $9.90 with rounding to the nearest tenth
