\(D,E,F\) are respectively the points on the sides \(BC,CA\) and \(AB\) of a \(\triangle ABC\), dividing them in the ratio \(2:3,\;1:2,\;3:1\) internally. The lines \(BE\) and \(CF\) intersect on the line \(AD\) at \(P\). If
\[
\overrightarrow{AP}=x_1\overrightarrow{AB}+y_1\overrightarrow{AC},
\]
then
\[
x_1+y_1=
\]
