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 12 by the denominator 3:
12 (numerator) ÷ 3 (denominator) = 4
As a result, you get 4 as your answer when you convert 12/3 to a decimal.
