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 93 by the denominator 15 (which you can enter in any calculator):
93 (numerator) ÷ 15 (denominator) = 6.2
And finally, you get 6.2 as your answer when you convert 2 63/15 (or 93/15) to a decimal.
