What was the main reason for truman’s decision to drop the atomic bomb on japan?

Saving American lives was Truman's deciding factor for dropping the atomic bomb on Japan

the three-fifths compromise was proposed by james wilson and roger sherman, who were both delegates for the constitutional convention of 1787. however, the three-fifth compromise has its roots further back in history, dating back to the continental congress in 1783. the compromise was a result of the apportionment of taxes being related to land values.

hope this : )
