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 56 by the denominator 15 (which you can enter in any calculator):
56 (numerator) ÷ 15 (denominator) = 3.73
And finally, you get 3.73 as your answer when you convert 2 26/15 (or 56/15) to a decimal.
