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 63 by the denominator 4:
63 (numerator) ÷ 4 (denominator) = 15.75
As a result, you get 15.75 as your answer when you convert 15 3/4 (or 63/4) to a decimal.
