During the constitutional convention, what issue did the three-fifths compromise attempt to solve?

The Three-Fifths Compromise attempted to solve the problem that arose from the value of slaves in population censuses that would determine the representation of each state in Congress.

Explanation:

The Three-Fifths Compromise was a compromise between the southern and northern states of the United States that was reached at the 1787 Constitutional Convention in Philadelphia. It was determined that three out of five of the slaves should be included in the state census, both for tax purposes and for seat allocation in the House of Representatives. This gave the southern states a third more congressmen and electors for the election of the President than if slaves were not to be counted. However, their dominance of politics in the interests of slave owners until the outbreak of the Civil War in 1861 had to be paid through higher taxes.
