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 3675 by the denominator 55 (which you can enter in any calculator):
3675 (numerator) ÷ 55 (denominator) = 66.82
And finally, you get 66.82 as your answer when you convert 65 100/55 (or 3675/55) to a decimal.
