Putting Numbers into Perspective A large number can be put into perspective by comparing it with another number. For example, we put the $ 15.2 trillion national debt (Example 9) and the $2.17 trillion the government collected in taxes (Exercise 111) into perspective by comparing these numbers to the number of US. citizens.
For this project, each group member should consult an almanac, a newspaper, or the Internet to find a number greater than one million. Explain to other members of the group the context in which the large number is used. Express the number in scientific notation. Then put the number into perspective by comparing it with another number.
