The delegates to the Constitutional Convention resolved their disagreement regarding slavery by agreeing that 60 percent of a state's slave population would be counted for purposes of both representation and taxation. This was called the Three-Fifths Compromise.

Explanation:

The Three-Fifths Compromise was a compromise established at the 1787 Philadelphia Convention between the North and South states. This compromise considered, in the counting rules of persons represented in the House of Representatives, that a slave was counted for three-fifths of a free man. This compromise proposed by James Wilson and Roger Sherman was included in the United States Constitution, in Article 1, Section 2, Clause 3.

The question was important because the population count would then be used to determine how many seats each state would have in the US House of Representatives. The Compromise gave a disproportionate representation to slave states in the House of Representatives compared to voters in free states until the Civil War.
