Point C should have 1/3a and 2/3 b

Look at the diagram and you will find 6 triangles that make up OA and OB.

so 1/3 into 6 with give you two. You go two triangles up from Origin in the direction of OA.

Now you multiply 2/3 into 6 which will give you 4. Go 4 triangles in the direction of OB and you will get point C.

This is how i did it.

Apply these methods for part ii and you will get the answer.

and for part iii . subtract OB from OE to get the answer.
