Answer: Congress must call a convention for proposing amendments upon application of the legislatures of two-thirds of the states
Explanation:
Congress must pass a proposed amendment by a two-thirds majority vote in both the Senate and the House of Representatives and send it to the states for ratification by a vote of the state legislatures.
1) Both houses propose an amendment with a two-thirds vote, and three-fourths of the state legislatures approve. (Twenty-six of the 27 amendments were approved in this manner)
2) Both houses propose an amendment with a two-thirds vote, and three-fourths of the states approve the amendment via ratifying conventions.
