6. Article Seven requires that nine states ratify the Constitution in order for

the new government to begin. What percent of the states needed to

approve? How does that compare with the three-quarters needed to

approve an amendment?

The states that need to ratify a constitution for it to become legal are nine states, that is 70% approval over the required threshold of thirteen states for amendment proposals to states which require all the 75% of the total states threshold.

Explanation:

Article seven of the US constitution provides that, in the event where, nine member states ratify a constitution (70%) then, it is qualified to pass as legal.

Differently, the approval of an amendment to the states must comply with the law that requires it to be ratified by at-least 75% of the total, which is higher by 5% compared to the one for ratification of the constitution.
