Step-by-step explanation:
The delegate from Connecticut who was responsible for introducing the Great Compromise and the 3/5th's Compromise was Roger Sherman.
The Great Compromise, also known as the Connecticut Compromise, was proposed by Roger Sherman during the Constitutional Convention in 1787. It suggested a bicameral congress with the upper house, the Senate, having equal representation for each state, and the lower house, the House of Representatives, having representation based on a state's population.
The 3/5th's Compromise, also proposed by Roger Sherman, addressed the issue of slavery and counted slaves as three-fifths of a person for the purpose of determining both representation and taxation.
