Each marked unit on the number line represents 0.25.
-1.5< -1< -0.75< 2
Practice makes perfect
We are asked to order the given numbers from least to greatest.
-1.5, -0.75, -1, 2
To do this, we will first add all the numbers to the given number line. Notice that each marked unit represents 0.25.
The first number we will write on the number line is -1.5. This will be placed 1 and one-half to the left of 0. We can also think about this as putting the circle two marked units to the left of -1 because each marked unit represents 0.25.
Next let's write -0.75. It is three marked units to the left of 0.
The next number is -1.
The last number to plot is 2. It is a positive number, so it is to the right of 0.
Finally, we can order the numbers from least to greatest. The least number is -1.5 because it is the farthest to the left. The greatest number is 2 because it is the farthest to the right.
-1.5< -1< -0.75< 2
