My number has 2 hundreds. The tens digit is 9 more than the ones digit. My number is?
If the number has 2 hundreds we know the first digit is 2. So far our answer is 2... If the tens digit is 9 more than the ones digit than the only possible answer would be 290 because 9 more than 0 is 9. So the final answer is 290. Hope I helped:D
