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 12000 by the denominator 107 (which you can enter in any calculator):
12000 (numerator) ÷ 107 (denominator) = 112.15
And finally, you get 112.15 as your answer when you convert 112 16/107 (or 12000/107) to a decimal.
