What is one compromise made at the constitutional convention

There were two main compromises made at the Constitutional Convention; the Great Compromise, and the 3/5ths compromise.

The “Great Compromise,” was: the small states got equal representation (two Senators from each state) in the Senate, and the large states got proportional representation based on population in the House.

The 3/5ths compromise was when the North, who didn't have slaves, wanted slaves to not be represented when deciding the amount of representation in Congress, while the South, in order to gain more representation, wanted all slaves to be counted. So, the 3/5ths compromise was born. The 3/5ths compromise was that all slaves would be counted as 3/5ths of a person. So, not a whole person, but sill counted somewhat.
