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 1496 by the denominator 124 (which you can enter in any calculator):
1496 (numerator) ÷ 124 (denominator) = 12.06
And finally, you get 12.06 as your answer when you convert 11 132/124 (or 1496/124) to a decimal.
