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 144 by the denominator 3:
144 (numerator) ÷ 3 (denominator) = 48
As a result, you get 48 as your answer when you convert 12 108/3 (or 144/3) to a decimal.
