Consider a parallelogram with vertices at $(15,60)$, $(15,144)$, $(36,192)$, and $(36,108)$. Determine the slope of a line passing through the origin that divides this parallelogram into two congruent polygons. Express the slope as a simplified fraction $m/n$, where $m$ and $n$ are relatively prime integers, and find $m+n$.
