Since the United States has 50 states (as of 2014), you can take the number of states and divide by 50.
The United States is on both sides of the Mississippi
Illinois and Kentucky border both the Mississippi and Ohio rivers.
When the Ohio River joins the Mississippi River, the three states that come together are Illinois, Kentucky, and Missouri. The confluence of these rivers serves as a natural boundary between these states. This area is significant both geographically and historically, as it has been a vital waterway for transportation and trade.
Louisiana
Wisconsin, Illinois, Kentucky, Tennessee, and Mississippi are along the east side of the Mississippi River. The river also flows through Minnesota and Louisiana so that it is on both sides of the river in those states.
The Mississippi River empties into the Gulf of Mexico. This major body of water is located to the south of the river's mouth, where it flows into the Gulf after traversing through several states in the United States. The river's delta region is a vital ecological area and plays a significant role in both the environment and the economy.
The Columbia River forms part of the border between Washington State and Oregon. Both of these states are West of the Mississippi River.
The borders of Wisconsin, Illinois, Kentucky, Tennessee, and Mississippi are along the east side of the Mississippi River. The river flows through Minnesota and Louisiana so that the river is on both the eastern and western banks in those states.
Both states touch the Mississippi River
Two of the United States biggest rivers meet in St Louis Missouri. The Mississippi River and the Missouri River both meet in St Louis.
