Answer :
The answer is a simple majority of Congress. The Congress, at whatever point 66% of both houses should esteem it essential, might propose corrections to this Constitution, or, on the use of the lawmaking bodies of 66% of the few states, should call a tradition for proposing revisions.
An ammendment of the Constitution can be proposed by the Congress. A two-thirds majority vote in the Senate and house of representatives or by a constitutional convention. This convention is called for by two thirds of the State of Legislature. So far, none of the 27 amendments of the Constitution have been proposed by contutional convention.
