A fraction is usually split into two parts: the first part is the number on top, called the numerator; and the second part is the number on the bottom, called the denominator. These are both separated by a line called the “divisor line”. We can use the division method help to solve this question: to get a decimal, simply divide the numerator 5298 by the denominator 68 (which you can enter in any calculator):
5298 (numerator) ÷ 68 (denominator) = 77.91
And finally, you get 77.91 as your answer when you convert 77 62/68 (or 5298/68) to a decimal.
