A fraction is written in terms of two parts: the number on top is called the numerator and the number on the bottom is called the denominator. We can use the division method to solve this question. To get a decimal, simply divide the numerator 122 by the denominator 12:
122 (numerator) ÷ 12 (denominator) = 10.17
As a result, you get 10.17 as your answer when you convert 10 2/12 (or 122/12) to a decimal.
