0.12 does not equal 12. This is because 12 is after the decimal, so it would be 12 hundredths. This about it this way: if you have 1.5, you wouldn't say 15, you would say 1 point 5, or 1 half. Same thing with this problem.
The answer is 91 because the tens place has to be 8 more so in the 80's, 8 would be 8 more than 0 and 0 is not one of the digits and it's a 2 digit number so it can't go to the 100's so 91 is the best answer. I hope this helped you
