Answer:
3.027, 3.27, 3.2742, 3.3
Explanation:
First list the numbers:
3.027
3.2742
3.27
3.3
Add the zero to the numbers without 4 decimal places so that they are equal.
Now you have:
3.0270
3.2742
3.2700
3.3000
Look at the number with the lowest number on the first decimal place, which is 3.0270. This becomes the lowest number. Then move on to the next decimal place. 3.2700 and 3.2742 both have the same digits on the first two decimal places. Look at the third decimal place between the two and you can see that 0 (on 3.2700) is lower than 4 (on 3.2742).
So now we have:
3.0270, 3.2700.
Then looking at the last two you have 3.2742 and 3.3000. In this case it's clear that 3.2742 is smaller so we put it as the third.
The order is as follows:
3.0270 (3.027)
3.2700 (3.27)
3.2742 (3.2742)
3.3000 (3.3)
