The article that explains how the Constitution will be ratified, approved, and take effect is Article VII of the United States Constitution. Article VII describes the ratification process for the Constitution, stating that the Constitution would become established and operational after ratification by nine of the thirteen original states. Once the required nine states ratify, the Constitution takes effect between those states, and the government can begin operating under the new Constitution. No further approval is necessary beyond this ratification threshold for the Constitution to take effect. Additionally, Article V explains the procedure for amending the Constitution after its establishment, detailing how amendments must be proposed and ratified to take effect. However, the initial ratification and approval of the Constitution itself is governed by Article VII. This is summarized as follows:

• Article VII establishes the procedure for initial ratification of the Constitution.
• Ratification by nine states is sufficient for the Constitution to become effective.
• After ratification, the operational government begins, as scheduled by Congress.
• No further congressional or other formalities are needed for the Constitution to take effect after ratification.

These points clarify the Constitution's ratification and effect in terms of approval and operational commencement.
