Sorted by: 2. G / N being the homomorphic image of G / G ′ means that there is a surjective homomorphism φ: G / G ′ → G / N. The existence of such homomorphism is an immediate result of the fundamental theorem of homomorphisms, since the kernel of the canonical projection G → G / N (which is N) contains G ′.
