Diagram showing C on OA, M on AB and D beyond B on OB, with OA labelled 5a and OB labelled 3b.

\vec{OA} = 5\mathbf{a}

\vec{OB} = 3\mathbf{b}

$C\,$ is the point on $OA\,$ such that $O C : C A = 4 : 1$ $M\,$ is the midpoint of $A B$ $D\,$ is the point such that $O B : O D = 3 : 4$

Show that $C$ , $M\,$ and $D\,$ are on the same straight line.
