How did delegates solve the problem of state representation in congress?

Delegates at the Constitutional Convention solved the problem of state representation in Congress through the Great Compromise (or Connecticut Compromise). This agreement established a bicameral legislature, consisting of the House of Representatives, where representation is based on population, and the Senate, where each state has equal representation with two senators. This compromise balanced the interests of both large and small states, allowing for fair representation while ensuring that all states had a voice in the legislative process.
