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 773 by the denominator 9864 (which you can enter in any calculator):
773 (numerator) ÷ 9864 (denominator) = 0.08
And finally, you get 0.08 as your answer when you convert 773/9864 to a decimal.
