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 66 by the denominator 4:
66 (numerator) ÷ 4 (denominator) = 16.5
As a result, you get 16.5 as your answer when you convert 13 14/4 (or 66/4) to a decimal.
