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 121 by the denominator 11:
121 (numerator) ÷ 11 (denominator) = 11
As a result, you get 11 as your answer when you convert 3 88/11 (or 121/11) to a decimal.
