Answer:
22%, 0.3,

Now to change
to a percentage. Simply divide 19 by 40.
19 ÷ 40 = 0.475

The decimal is now 47.5%.
22% is already a percentage.
Now, let's compare.
30%, 47.5%, 22%
The greatest number seems to be 47.5%, while the least is 22%.
Let's organize it from least to greatest.
22%, 30%, 47.5%
Now, change the percentages back to their original numbers.
47.5% = 
30% = 0.3
22% = 22%
22%, 0.3,
