To put the numbers in order from least to greatest, let's convert all of them to decimal form:
- 13: This is already a whole number (13.0).
- 4/5: When converted to decimal, 4/5 = 0.8.
- 0.9: This is already in decimal form (0.9).
- 7/35: This simplifies to 1/5 = 0.2, which in decimal form is 0.2.
- -13.5: This is already in decimal form (-13.5).
Now we have:
- 13.0
- 0.8
- 0.9
- 0.2
- -13.5
Now we can arrange them in order from least to greatest:
- -13.5
- 0.2
- 0.8
- 0.9
- 13.0
So the final order from least to greatest is:
- -13.5, 0.2, 0.8, 0.9, 13.0
