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 8:
51 (numerator) ÷ 8 (denominator) = 6.38
As a result, you get 6.38 as your answer when you convert 4 19/8 (or 51/8) to a decimal.
