Answer:
A) To determine how slaves would be counted toward state populations
Explanation:
The 3/5 Compromise was an agreement between the northern and southern US states to figure out how they would count slaves in the population.
It stated that 3/5 of the slave populations would be counted to determine seats in the House of Representatives and electoral votes.
Because the North wanted to abolish slavery and the South didn't because they were making some serious money.
