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 149 by the denominator 31:
149 (numerator) ÷ 31 (denominator) = 4.81
As a result, you get 4.81 as your answer when you convert 3 56/31 (or 149/31) to a decimal.
