James Madison proposed 12 amendments to the Constitution, 10 of which were approved. The ones that weren't would have established Congressional representation and prohibited Congress from raising its own salaries.
Constitutional amendments must first pass both houses of congress, and they are then sent to the states to be ratified. To become a law, 3/4 of the states must agree to ratify an amendment. This is to make sure that amending the constitution is difficult and requires a lot of thought before it happens. So, to sum up, after a proposed amendment is approved by congress, it must then go to the individual states; if enough states vote to approve it, the amendment becomes a part of the constitution.
