Student Lesson Summary
When ordering rational numbers from least to greatest, they can be listed in the order they appear on the number line from left to right. For example, we can see that the numbers
-2.7, -1.3, 0.8
are listed from least to greatest because of the order they appear on the number line.
On a horizontal number line, numbers to the left are smaller than numbers to the right. We can say that -2.7 is less than -1.3. We can write .
Similarly, numbers to the right are greater than numbers to the left. We can say that 0.8 is greater than -2.7. We can write .
