The first one:
The Constitution provides that an amendment may be proposed either by the Congress with a two-thirds majority vote in both the House of Representatives and the Senate or by a constitutional convention called for by two-thirds of the State legislatures.
The second one:
- Passage by Congress. Proposed amendment language must be approved by a two-thirds vote of both houses.
-Notification of the states. The national archivist sends notification and materials to the governor of each state.
-Ratification by three-fourths of the states. ...
-Tracking state actions. ...
-Announcement.
Hope this helps, and no it's not plagiarized :)
Have a good night.
