In parallelogram EFGH, let M be the point on ¯EF such that FM:ME=3:5, and let N be the point on ¯EH such that HN:NE=2:5. Line segments ¯FH and ¯GM intersect at P, and line segments ¯FH and ¯GN intersect at Q. Find PQFH.

Triangle HQN similar to Triangle FQG
HN / FG = 2 / 7
Therefore HQ / FQ = 2 / 7
Therefore HQ / (HQ + FQ) = HQ / HF = 2 / ( 2 + 7) = 2/9 ⇒ HQ = (2/9) HF
Triangle PFM similar to Triangle PHG
FM / HG = 3 / 8
Therefore PF / PH = 3 / 8
Therfore PF / (PF + PH) = PF / HF = 3 /( 3 + 8) = 3 / 11 ⇒ PF = (3/11) HF
Getting a common denominator between 9 and 11
HQ = 22/99FH
PF = 27/99 FH
Therefore
FH - HQ - PF = PQ
FH - (22/99)FH - (27/99)FH = PQ
(50/99)FH = PQ
Therefore
PQ / FH = 50 / 99
