Answer:
The disagreement leading to the 3/5th compromise was whether or not slaves should count as a person for representation in the House. The North and South opposed each other, the South saying they should and the North saying they shouldn't. Both sides were scared of losing power in congress. The South argued that since slaves lived in the state they should count towards representation. The North argued that since slaves were not citizens and had no say in government they should not count towards representation. The compromise was that slaves would count as 3/5th of a person towards representation. This set a precedent in America that slaves were less than a person, this was one cause of the Civil War.
