In triangle $ABC$, $AB=15$ and $AC=9$. The angle bisector of $\angle A$ intersects $BC$ at point $D$, and point $M$ is the midpoint of $AD$. Let $P$ be the point of the intersection of $AC$ and $BM$. Find the ratio of $CP$ to $PA$ and express it in the form $\dfrac{m}{n}$, where $m$ and $n$ are relatively prime positive integers. What is $m+n$?
