To compare the numbers easily, let's convert all of them to decimal form:
- 13 = 13.0
- 45 = 45.0
- 0.9 = 0.9
- 735 = 735.0
- -13.5 = -13.5
Now, we can order them from least to greatest:
- -13.5
- 0.9
- 13.0
- 45.0
- 735.0
So, in order from least to greatest, the numbers are:
-13.5, 0.9, 13, 45, 735
