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 8818 by the denominator 87 (which you can enter in any calculator):
8818 (numerator) ÷ 87 (denominator) = 101.36
And finally, you get 101.36 as your answer when you convert 100 118/87 (or 8818/87) to a decimal.
