Let's look at the answers:

0.801 - We'll add 0 to our number and compare between 0.810 and 0.801, since the hundredths digit is 0 and 0 is less than 1, this is the correct answer.

0.81 - Since both numbers are equal to each other, this is not the correct answer.

0.82 - Since the hundredths digit is 2 and 2 is greater than 1, this is not the correct answer.

0.822 - We'll add 0 to our number and compare between 0.810 and 0.822, since the hundredths digit is 2 and 2 is greater than 1, this is not the correct answer.
