The bylaws may provide the number or percentage of members entitled to vote represented in person or by proxy, or the number or percentage of votes represented in person or by proxy, that constitutes a quorum at a meeting of members. In the absence of any provision, members holding one-tenth (1/10) of the votes entitled to be cast on the matter to be voted upon represented in person or by proxy constitute a quorum. If a quorum is present, the affirmative vote of a majority of the members present or represented by proxy is the act of the members unless a greater proportion or voting by classes is required by this chapter, the articles of incorporation, or the bylaws.
