Final answer:
At the Constitutional Convention, slavery was a contentious topic, and the Three-Fifths Compromise was eventually reached to count each enslaved person as three-fifths for both representation and taxation.
Step-by-step explanation:
The Constitutional Convention in Philadelphia in 1787 addressed various issues, including slavery which was a contentious topic. The question of how to account for enslaved populations in states' representation was particularly divisive. Ultimately, the Three-Fifths Compromise was reached, which stipulated that a state's enslaved population would count as three-fifths of a person for both representation and taxation purposes. This resolution allowed for the continuation of slavery within the constitutional framework, contributing to the ongoing debate and conflict over the institution in the United States.
