There are no such numbers. The sum of any three odd numbers must be odd. 112 is not.

None that are all odd numbers. But, there are two sets of three consecutive numbers containing a mix of even/odd that add up to 120. They are 39, 40 and 41 and also 38, 40 and 42.
There are no numbers that equal 112, except for 112. Also, it's not possible to ADD three odd numbers and get 112 for their sum.

No three odd numbers can add up to an even number.
The sum of three odd numbers is odd but 270 is even, therefore there are no three odd numbers that add to 270. Similarly the product of two of more odd numbers is odd but 270 is even, therefore there are no three odd numbers that multiply together to get 270.

Well, darling, those three odd consecutive numbers that add up to 252 are 83, 85, and 87. You add them up and you get your grand total of 252. Voilà!

Sure! Three addition facts that have sums that are odd numbers are: 1+1=2 (even), 2+1=3 (odd), 3+3=6 (even).
The numbers are 11, 13 and 15.
