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 147 by the denominator 45:
147 (numerator) ÷ 45 (denominator) = 3.27
As a result, you get 3.27 as your answer when you convert 3 12/45 (or 147/45) to a decimal.
