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 148 by the denominator 12:
148 (numerator) ÷ 12 (denominator) = 12.33
As a result, you get 12.33 as your answer when you convert 1 136/12 (or 148/12) to a decimal.
