How do you put this in greatest to least 9.129 9.37 9.3 9.219?

Answer 1

They are start with 9, but have different amount of decimal places. If we put them all into 3 decimal places by adding extra zeros where necessary, it makes them easier to compare and then sort. So they will first be:

9.129 , 9.370, 9.300, 9.219

Sorting them and removing the trailing zeros, they become:

9.37, 9.3, 9.219, 9.129

Answer 2

9.3,9.37,9.129,9,219

Answer 3

9.37, 9.3,9.219,9.129
