The topic that was common to the Virginia Plan, the New Jersey Plan and the Three-Fifhts Compromise was how to distribute and assign the seats in Congress.
The Virginia Plan, also known as Large State Plan, proposed that the seats both in the House of Representatives and the Senate should be distributed in proportional fashion, that is, states with larger populations would have more seats.
The New Jersey Plan (also called the Small State Plan), on the other hand, was based on a Congress that had only one chamber, where all the states would have the same number of representatives (only one).
The Three-Fifths Compromise was a way to calculate the population of the states in order to appoint representatives: every slave would count as three-fifths of a white person.
