Vectors Proof Questions

A vector diagram shows a triangle $O J K$ .

\vec{OJ} = 5\mathbf{j}

\vec{OK} = 2\mathbf{k}

$L\,$ is the point on $JK\,$ such that $J L : L K = 1 : 4$

\vec{OL} = n(10\mathbf{j} + \mathbf{k})

Vector diagram of triangle OJK with L on JK in the ratio JL to LK equals 1 to 4, showing vectors OJ, OK and OL.

Find the value of $n$ .
