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 9696 by the denominator 80 (which you can enter in any calculator):
9696 (numerator) ÷ 80 (denominator) = 121.2
And finally, you get 121.2 as your answer when you convert 120 96/80 (or 9696/80) to a decimal.
