You can put this solution on YOUR website! 201 -- Since we know that it must be less than 300, the largest its 100s digit could at most be 2. From the last part of the statement "my ones digit is less than my hundreds digit" we know that the largest the ones digit could be is 1. Given also that "my tens digit is less than my ones digit" we know the largest that the tens digit can be is 0. Since 0 is also the smallest number, it's also the ONLY number the 10's place can be. The number with a 2 in the 100's place, a 0 in the 10's and a 1 in the ones is 201.

Let these three blanks represent the 3-digit
number.
>>...I am a 3 digit number less than 300...<<
Therefore the number is 1 or 2
>>...my ones digit is less than my hundreds digit...<<
So the number is either 1 0, 2 1, or 2 0
>>...My tens digit is less than my ones digit...<<
This rules out 1 0 and 2 0, because there is no digit less than 0.
So that leaves only 2 1, and the only digit less than 1 is 0, so the
tens digit is 0, and the number is
2 0 1
