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 871400 by the denominator 108800 (which you can enter in any calculator):
871400 (numerator) ÷ 108800 (denominator) = 8.01
And finally, you get 8.01 as your answer when you convert 8 1000/108800 (or 871400/108800) to a decimal.
