Given :
439.216, 439.126, 439.612, 439.261
From decreasing means order from highest to lowest number
To do that look at the first digit (from left to right ) , all are 4
Then the second digit, all are 3
Then the third digit , all are 9
Then the 4th.
We have:

6 , 2 , 2 , 1
For the numbers that have the same 4th digit (2) look at the 5th digit
1 , 6
Now, write the whole numbers in order:
439.612 - 439.261 - 439.216 - 439.126
Answer:
439.612 - 439.261 - 439.216 - 439.126
