All provisions in the existing laws referring to the select and common councils of said city, and all powers, rights, and duties, which by existing laws devolve upon the members of select or common councils, shall be taken to apply to and be vested in the council created by this act, as fully and to the same extent as though the present council were therein named, in so far as the same are not inconsistent with the foregoing rights, powers, and duties. And whenever any proportionate affirmative vote of each branch of councils, as at present constituted, is required under existing laws to ordain or enact any ordinance or resolution, the same proportionate affirmative vote of the council hereby created shall be sufficient for the passage thereof.
