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 13500 by the denominator 2680 (which you can enter in any calculator):
13500 (numerator) ÷ 2680 (denominator) = 5.04
And finally, you get 5.04 as your answer when you convert 5 100/2680 (or 13500/2680) to a decimal.
