Approval by each State legislature means majority approval by all members of each House in the State’s legislative branch.

Any approval by the legislatures of the States as used in the Constitution means approval by a majority of all members of each House in their legislative branch.

This amendment is solely for the purpose of clarifying that a majority of both Houses of any State legislature is required for legislative approval and that such approval is of the whole number of legislators in each House and not a majority of a quorum.
