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 18:
78 (numerator) ÷ 18 (denominator) = 4.33
As a result, you get 4.33 as your answer when you convert 4 6/18 (or 78/18) to a decimal.
