A properly established club or civic group typically has a constitution, articles of incorporation, statement or organization, or similar, and bylaws. You should obtain copies of these, and review them for the proper procedures for holding meetings, establishing a quorum, proposing motions, and voting.
Most organizations follow Roberts Rules of Order as the rules for conducting meetings. One or more of the above documents should state so, and which edition. You should get a copy for yourself, and be prepared to apply the rules so as to conduct the meetings and votes per the proper procedures.
