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 105 by the denominator 31:
105 (numerator) ÷ 31 (denominator) = 3.39
As a result, you get 3.39 as your answer when you convert 1 74/31 (or 105/31) to a decimal.
