Order these numbers from least to greatest?

Change the first two numbers into decimals:
5 6/25 = 5.24
21/4 = 5.25

Since 5.24 < 5.244 < 5.25 < 5.98,
then 5 6/25 < 5.244 < 21/4 < 5.98

Order these numbers  [5 6/25 ,21/4, 5.244, 5.98]
from least to greatest:
                                      5.24, 5.244, 5.25, 5.98

They are: 5 6/25 = (5.24), 5.244, 21/4 = (5.25) and 5.98 from least to greatest
