Final answer:
The 3/5ths Compromise was implemented to include slaves in the Southern states' population count for representation in the House of Representatives.
Step-by-step explanation:
The main purpose of the 3/5ths Compromise was that the Southern states wanted slaves to be counted towards their population so they could have more representatives in the House of Representatives. Under this compromise, slaves were counted as three-fifths of a person for the purpose of determining representation in the House. This gave Southern states more political power as they had a larger population count.
