1. ## Vector geometry - problem solving

i have a question to solve using vector geometry.
In a parallelogram ABCD, the points P and Q dividing each of the sides AD and DC in the ratio 1:4.
if Vector DA = a and vector DC = b, find
(i) The ratio which R divdes DB
(ii) The ratio which R divdes PQ

thanks
