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 129 by the denominator 11:
129 (numerator) ÷ 11 (denominator) = 11.73
As a result, you get 11.73 as your answer when you convert 10 19/11 (or 129/11) to a decimal.
