It all comes down to a matter of math and a few important numbers: 5, 27, 34, 38, 535 and 9. The current debate is about a movement to call a convention of states to propose a balanced budget amendment, instead of leaving that task to Congress. Article V of our Constitution lays out two ways to amend the current document. One way has been used 17 times since the 10 amendments in the Bill of Rights were ratified in 1791. So far, these 27 amendments have originated in Congress and been sent to the states for approval. Once three-quarters of the individual states ratify an amendment, it becomes the law. The second method has never been used.
