Answer:
Section 2 of the Fourteenth Amendment to the United States Constitution.
Step-by-step explanation:
The Three-Fifths Compromise of the US Constitutional Convention is an agreement between the Northern and Southern states of America regarding the manner of population count that needs to be done for the basis of taxation and determining representation in the House of Representatives. This agreement is famous for its decision to count only three-fifths of the slave population for the population count.
This agreement not only wrongly number the slave population thereby leading to lesser representation in the House, but it also prevents landowners from paying the full tax on their property as only three-fifths of their slaves were accounted for.
This Compromise was later rendered moot or useless by the Fourteenth Amendment of the United States Constitution in its Section 2. As Section 2 of the Amendment states "Representatives shall be apportioned among the several States according to their respective numbers, counting the whole number of persons in each State, excluding Indians not taxed."
