The Three Fits compromise benefits which stas?

Because Southern states had many more slaves than did Northern states, the Three-Fifths Compromise benefited Southern states more than it did Northern states in terms of representation in the House of Representatives.

The compromise solution was to count three out of every five slaves as people for this purpose. Its effect was to give the Southern states a third more seats in Congress and a third more electoral votes than if slaves had been ignored, but fewer than if slaves and free people had been counted equally.
