If a quorum is present, the affirmative vote of the majority of the voting power represented at the meeting, entitled to vote, and voting on any matter shall be the act of the members.

(b) The members present at a duly called or held meeting at which a quorum is present may continue to transact business until adjournment notwithstanding the withdrawal of enough members to leave less than a quorum, if any action taken (other than adjournment) is approved by at least a majority of the members required to constitute a quorum or, if required by this division, or by the articles or the bylaws, the vote of the greater number or voting by classes.

(c) In the absence of a quorum, any meeting of members may be adjourned from time to time by the vote of a majority of the votes represented either in person or by proxy, but no other business may be transacted, except as provided in subdivision (b).
