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 120:
12 (numerator) ÷ 120 (denominator) = 0.1
As a result, you get 0.1 as your answer when you convert 12/120 to a decimal.
