In the absence of any provision, members holding one-tenth of the votes entitled to be cast on the matter to be voted upon, represented in person or by proxy, shall constitute a quorum. A majority of the votes entitled to be cast on a matter to be voted upon by the members present or represented by proxy at a meeting at which a quorum is present shall be necessary for any action to be taken unless a greater proportion is required by this title or this chapter or by the nonprofit corporation's governing documents.
