majority
They must have present 2/3 of their members.
Half of the members plus 1
The Constitution of the United States says that 2/3 of the Congressmen need to be present to do business. That means that 67 Senators and 291 House of Representatives need to be present during sessions.
Congress must have a 'quorum'. That means that at least half of the members must be present. That would be 50 in the Senate and 219 in the House.
The quorum is 218. This is the minimum amount of people needed to conduct business. This makes sense because there are 435 total members in the House of Representatives and 217.5 is exactly half.
A quorum is the smallest number of members who must be present for business to be conducted. Each house can set its own rules about absent members. The minimum number of members of an assembly or society that must be present at any of its meetings to make the proceedings of that meeting valid.
That depends on the rules set up by the specific committee, but a common requirement is that MORE THAN HALF of the members be present.
A simple majority is anything more than a half, in this case 218 or more. However is cases where the are many members of a house or committee a lower limit is set on the actual number of people voting, either for or against, before a decision can be made. This is called a quorum. If the number of people voting is below this number then the voting is invalid and not binding..
The Constitution requires that at least one half of the members of Congress be present in order to vote on a bill. Without that amount, a vote cannot be held.
One more than half of those voting in favor passes a bill unless it is a bill that the President has vetoed and sent back. In this latter case, two-thirds of those voting must vote in favor of it. The House has an odd number of members so a tie is impossible if everybody votes . In the Senate which has an even number of members, the Vice-President who presides over the Senate can vote to break a tie vote.
a QUORUM is defined as more than half the members present
