The delegates compromise was the great compromise (also known as the new jersey plan) in which the house would be divided into the house of representatives where the number of representatives would be based on population and the senate where each state would be given 2 representatives. This led to the problem of slaves and such the 3/5 compromise was born where a slave counted as 3/5 of a person.
The main benefit of slavery to governments in the colonies is that it provided a system of almost entirely free labor, since the slaves were not compensated for their work, which took place primarily in fields. <span />
