Answer: They were partially counted in the census.
Step-by-step explanation:
Three-fifths compromise, was a compromise agreement that took place between delegates from both Southern and Northern states in 2787 at United States Constitutional Convention and the compromise was that about three-fifths of the population of the slaves would be counted for while determining both direct taxation and also the representation in the Representatives.
The agreement that the delegates reach regarding enslaved people and representation with the Three-Fifths was that they were partially counted in the census.
