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 30 by the denominator 9:
30 (numerator) ÷ 9 (denominator) = 3.33
As a result, you get 3.33 as your answer when you convert 2 12/9 (or 30/9) to a decimal.
