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 146 by the denominator 31:
146 (numerator) ÷ 31 (denominator) = 4.71
As a result, you get 4.71 as your answer when you convert 3 53/31 (or 146/31) to a decimal.
