Answer:
Step-by-step explanation:
An amendment may be proposed by a two-thirds vote of both Houses of Congress, or, if two-thirds of the States request one, by a convention called for that purpose. The amendment must then be ratified by three-fourths of the State legislatures or three-fourths of conventions called in each State for ratification.
The Constitution provides that an amendment may be proposed either by 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.
