To place the numbers in order as you would see on a number line, we need to arrange them from the smallest to the largest. Here are the given numbers:
- -13.1
- -2.99
- 0.199
- 5.6
- 6 ½ (which is equivalent to 6.5)
Now, let's list them in order:
- -13.1
- -2.99
- 0.199
- 5.6
- 6.5
So, in order from least to greatest, we have:
-13.1, -2.99, 0.199, 5.6, 6.5
