Final answer:
To compare rational numbers, use the symbols '>' (greater than) and '<' (less than) and compare them in order from greatest to least.
Step-by-step explanation:
To compare the given rational numbers in order from greatest to least, we can use the symbols '>' (greater than) and '<' (less than).
Comparing the numbers:
- 3 > 5 (3 is greater than 5)
- 5 > 0.827 (5 is greater than 0.827)
- 0.827 > 0.075 (0.827 is greater than 0.075)
- 0.075 > VI (0.075 is less than VI)
Therefore, the rational numbers in order from greatest to least are: 3, 5, 0.827, 0.075, VI.
