Thanks guys, I'll keep it in mind for next time. Either way, I got the question correct, so you guys helped a lot.
My professor actually went on to say during next class that we could round up or down and she would count either as correct. Also she stated that the ratio was inaccurate, but...
Just to give an answer to this question, my professor told me to round the ratio to the nearest whole number. Since it was 3.57 I should round it to 4, thus the correct answer would be C12H8O4.
Hmm, I guess I still don't understand what you're asking. Are you questioning the validity of the question, maybe it is wrong?
This is a general chemistry class I'm taking, I'm in my freshman year of college. The questions have been wrong a couple times before in previous assignments (and we've...

Well I think this one works?
2 + 3 + 4 + 5 = 14
1^2 = 1
2^2 = 4
3^2 = 9
4^2 = 16
It has to be the SUM of TWO squares... 9 + 4 = 13. None of the others work.
