0.354,0.47,0.481.0.5 would be the order from smallest to largest.
If you want to know an easy hint for the future, just put 0's on the ends until they all have the same amount of digits.
For this example, the max digits to the right of the decimal is 3.
0.354 (no change)
0.47---> 0.470
0.481 (no change)
0.5--> 0.500
Now ignore the 0 before the decimal (because they are all 0) and you will find the numbers a lot easier to order.
Hopefully that helps, let me know if you have any questions :)
