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 136 by the denominator 35:
136 (numerator) ÷ 35 (denominator) = 3.89
As a result, you get 3.89 as your answer when you convert 2 66/35 (or 136/35) to a decimal.
