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 11388 by the denominator 92 (which you can enter in any calculator):
11388 (numerator) ÷ 92 (denominator) = 123.78
And finally, you get 123.78 as your answer when you convert 123 72/92 (or 11388/92) to a decimal.
