NEED HELP ASAP 40 POINTS GEOMETRY QUESTION, PLEASE PUT FULL ANSWER!!!the lines listed below is the same line as the line with the equation??

To compare, you have to make the fraction/mixed number into decimals
6&4/9=6.4444444444444
127/20=6.35
every decimal has a whole of 6, so you need to look at the tenth's place, 4 is obviously larger than 3, so 6&4/9 is the largest.
the other three numbers all have a 3 in its tenth's place, so look at the hundredth's place, 9 is larger than 7, and 7 is larger than 5
so from the least to the largest:
127/20, 6.375, 6.39. 6&4/9
