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 15:
78 (numerator) ÷ 15 (denominator) = 5.2
As a result, you get 5.2 as your answer when you convert 78/15 to a decimal.
