Trivia: What portion of states does it take to ratify a Constitutional amendment?
One-half
Two-thirds
Three-quarters
All of them
The correct answer is Three-quarters
So why is this answer correct? : Amending the Constitution is not easy. Just to be proposed, an amendment has to be agreed upon by two-thirds of the Senate and two-thirds of the House of Representatives, or proposed by a convention of at least two-thirds of the states. To go from proposal to ratification is even tougher: It has to be ratified by state legislatures or conventions in three-quarters of all states.
