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 138 by the denominator 47:
138 (numerator) ÷ 47 (denominator) = 2.94
As a result, you get 2.94 as your answer when you convert 1 91/47 (or 138/47) to a decimal.
