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 139 by the denominator 121:

139 (numerator) ÷ 121 (denominator) = 1.15

As a result, you get 1.15 as your answer when you convert 139/121 to a decimal.
