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 26:
129 (numerator) ÷ 26 (denominator) = 4.96
As a result, you get 4.96 as your answer when you convert 2 77/26 (or 129/26) to a decimal.
