Before a proposed amendment can become part of the Constitution, it has to be passed by two-thirds of both houses of Congress and by three quarters of the individual states.

Explanation:

The constitutional amendment process is stated in Article Five of the United States Constitution. This article establishes that constitutional amendments may be proposed by agreement of Congress, through the approval of two thirds of both houses, or through a National Convention called by two thirds of the states through their legislatures.

In turn, once proposed, they must be approved by the legislatures of at least three quarters of the states of the Union (that is, at least 38 states must approve it) to be ratified.
