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 147 by the denominator 23:
147 (numerator) ÷ 23 (denominator) = 6.39
As a result, you get 6.39 as your answer when you convert 3 78/23 (or 147/23) to a decimal.
