Alright, let's see. Keep in mind I don't learn health really much at school so I'm not the best. In my opinion, I think it would be an answer that is fifteen something.

My final answer is..
Fifteen-twentieths.
I apologize badly if this is incorrect. If you don't feel comfortable with this answer you may put another answer. I recommend the answers that say "Fifteen" in front of them though. I sound so wrong-
