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 15610 by the denominator 120 (which you can enter in any calculator):
15610 (numerator) ÷ 120 (denominator) = 130.08
And finally, you get 130.08 as your answer when you convert 130 10/120 (or 15610/120) to a decimal.
