Answer: Slaves
Explanation: The Three-Fifths Compromise was an agreement made during the 1787 United States Constitutional Convention on the counting of slaves in order to establish a state's overall population.
The number of seats in the House of Representatives, the number of electoral votes each state would receive, and the amount of taxes each state would pay would all be determined by this count.
In order to allocate seats in the House of Representatives, the compromise included three-fifths of the slave population in each state's total population. Despite the fact that slaves were denied the ability to vote, this resulted in the South receiving more electoral votes for president and representatives than it would have otherwise.
