Final answer:
States needed to ratify the U.S. Constitution by a three-fourths majority for it to take effect. The framers agreed to add a Bill of Rights to address concerns of significant states, leading to ratification and the establishment of the new government.
Step-by-step explanation:
In order for the U.S. Constitution to be put into effect, the states had to ratify it by a consent of three-fourths. This ratification process was essential to the formation of the new government under the Constitution. The framers created a system where an amendment could become part of the Constitution once ratified by the required number of state legislatures. To ensure the Constitution’s adoption, the Federalists agreed to incorporate a bill of rights which resulted in the first 10 amendments. Article VII of the Constitution set out that the approval of nine of the thirteen states was necessary for the Constitution to become law, but for it to be effective, especially in larger states like New York and Virginia, the addition of a Bill of Rights to protect individual liberties became a decisive factor for ratification.
