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 1157 by the denominator 113 (which you can enter in any calculator):
1157 (numerator) ÷ 113 (denominator) = 10.24
And finally, you get 10.24 as your answer when you convert 9 140/113 (or 1157/113) to a decimal.
