Choose any number and check whether it is greater than 6.5.

Example Solution: - 600 meters
Other Numbers: all numbers less than - 400

Practice makes perfect
The elevation of the Dead Sea is less than - 400 meters. We want to choose a number that represents this situation.

Let's choose - 600 meters. - 600 < - 400 We know that - 600 is less than - 400. This means that - 600 meters is an example of the elevation of the Dead Sea. To find the other number that can represent the given situation, we can choose any number less than - 400.
