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 109 by the denominator 27:
109 (numerator) ÷ 27 (denominator) = 4.04
As a result, you get 4.04 as your answer when you convert 3 28/27 (or 109/27) to a decimal.
