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 120 by the denominator 3:
120 (numerator) ÷ 3 (denominator) = 40
As a result, you get 40 as your answer when you convert 120/3 to a decimal.
