I have two problems I need help with.
ABCD is a parallellogram. E is the midpoint on BC. F is on AD so that DF = 8AF. G is the intersection between AE and BF.
a) Express the vector AG as a linear combination of u = AB and v = AD.
b) Show that the area of the triangle AFG always is the same fractional part of ABCD. Find that fractional part!

I have no idae. Any help would be nice.
