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 78 by the denominator 109:
78 (numerator) ÷ 109 (denominator) = 0.72
As a result, you get 0.72 as your answer when you convert 78/109 to a decimal.
