the amendment proces, and camending the constitution itself
The Constitution of a country typically outlines the rules and procedures for its governance. In the case of the United States Constitution, a 3/4 majority is specified for certain processes, specifically for the ratification of amendments.
Getting the answer to this question requires consulting the United States Constitution. One way to access the Constitution is by visiting the official website of the U.S. Government at www.usa.gov. On the website, you can find a section specifically dedicated to the Constitution, where you can navigate and read the document in its entirety.
Upon reading the Constitution, specifically in Article V, you will find the information regarding the amendment process. To propose an amendment, either two-thirds (2/3) of both houses of Congress or two-thirds (2/3) of the state legislatures must vote in favor of it. However, to ratify an amendment, it requires the approval of three-fourths (3/4) of the state legislatures or state ratifying conventions. This 3/4 majority requirement ensures wide consensus and agreement before a constitutional amendment can become part of the United States Constitution.
