Answer:

AB = b - a


OP = (3)/(4) b \: + (1)/(4) a

Explanation:

AB = -OA + OB

AB = -a + b we usually write the positive vector first

AB = b - a

We know that P divides AB in the ratio 3:1 so PB = 1/4 AB

AB is negative as we are going in the opposite direction

OP = OB - 1/4 AB

OP = b - 1/4 (b - a)

multiplying inside the brackets:

OP = b - 1/4b + 1/4a

OP = 3/4b + 1/4a
