What is the range of the numbers?

key idea

The range is the difference between the greatest number and the least number.

solution

Read the numbers from the line plot. Each X represents one number.

First, find the greatest number. The greatest number is 9.

Next, find the least number. The least number is 5.

Subtract the least number from the greatest number:

9 − 5 = 4

The range is 4.
