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 77 by the denominator 4:
77 (numerator) ÷ 4 (denominator) = 19.25
As a result, you get 19.25 as your answer when you convert 15 17/4 (or 77/4) to a decimal.
