Arrange the following series in ascending order:
0.72, 11.201, 0.68, 8.03, 3.007 
This proceeds in the following steps:
Step 1: We start with comparing the Whole Number Part of Decimals and decimal with the smallest whole number part is to be written at first place in the order.
But, here in the given series you can see that there are two decimals having 0 as their whole number part, in such cases we will compare digits at tenths place and decimal with the smallest digit at tenths place will be 1st in the order and other decimal will be at 2nd place.
Decimal 0.72 has 7 at its tenths place
Decimal 0.68 has 6 at its tenths place
Since 6 is smaller than 7, so 0.68 will be at 1st place and 0.72 at 2nd place, get
Ascending Order Series = 0.68, 0.72
Step 2: Then we find a decimal whose whole number part is larger than the whole number part of decimal selected earlier in step 1, but smaller than whole number part of remaining decimals and we get:
3 is the whole number part of decimal 3.007
It is larger than the 0, which is the whole number part of decimals 0.68 & 0.72, but smaller than whole number part of remaining decimals.
So 3.007 is written next to decimals 0.72 in the ascending order and we get series:
Ascending Order Series = 0.68, 0.72, 3.007
Step 3: And then we find a decimal whose whole number part is larger than the whole number part of decimal selected earlier in step 2, but smaller than whole number part of remaining decimals and we get:
8 is the whole number part of decimal 8.03
It is larger than the 3, which is the whole number part of decimal 3.007, but smaller than whole number part of remaining decimals.
So 8.03 is written next to 3.007 in the ascending order and we get series:
Ascending Order Series = 0.68, 0.72, 3.007, 8.03
Step 4: Lastly, we are left with only one decimal, whose whole number part is the largest among whole number parts of all the given decimals and it would be written at the last place of the order,
Since decimal 11.201, whose whole number part is 11 and the largest among whole number parts of all the given decimals, so 11.201 would be written at the last place of the ascending order and we get complete series:
Ascending Order Series = 0.68, 0.72, 3.007, 8.03, 11.20
