Answer:
how to count slaves as population.
Step-by-step explanation:
The number of members that a state can send to the House of Representatives is depended by the amount of population that they have.
Southern states had a lot of slaves, but in 1787, those slaves weren't really acknowledge as legal citizens. The southern states argued that slaves should be counted as normal population while the northern states argued that they shouldn't count slaves as population.
As a result, they created a compromise in 1787. Slaves can be counted as population, but 1 slave can only be counted as 3/5.
