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 109 by the denominator 2 (which you can enter in any calculator):
109 (numerator) ÷ 2 (denominator) = 54.5
And finally, you get 54.5 as your answer when you convert 6 97/2 (or 109/2) to a decimal.
