ANSWER:
Three-fifths compromise was a law which was introduced in 1787. The law stated that slaves will be counted as three/fifth of a male or a female.
Step-by-step explanation:
For example, if there are a total of 5 slaves, then it will be counted as 3 persons out of the total population. Now consider number of people in a country, if '500 slaves' and 'five thousand citizens', the population will be counted as "five thousand three hundred" rather than "fifteen hundred".
