The Mississippi River is the second longest River in the United States , second only tho the Missouri River. The Mississippi River is about 23/25 the length of the Missouri River. If the Missouri River is 2,540 miles long how long is the Mississippi River ?
I would look at this as a percent. 23/25 is 92%. To find the percent of a number, make the percent a decimal and multiply. 2,540 times 0.92 is 2,336.8, so therefore the Mississippi is 2,336.8 miles long.
