Decimal Comparison: Finding Numbers Less Than 0.29

In order to determine the correct answer, let's compare our number with the numbers in the answers:

Observe the answers:

0.29 - Given that both numbers are equal to each other, this is not the correct answer.

0.3 - If we add 0 and compare 0.30 to 0.29, due to the fact that the tenths digit is 2 and 2 is less than 3, this is not the correct answer.

0.291 - If we add another 0 to our number and compare 0.290 to 0.291, owing to the fact that the thousandths digit is 1 and 1 is greater than 0, this is not the correct answer

0.28 - Since the hundredths digit is 8 and 8 is less than 9, this is the correct answer.
