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 51 by the denominator 4:
51 (numerator) ÷ 4 (denominator) = 12.75
As a result, you get 12.75 as your answer when you convert 51/4 to a decimal.
