A fraction is written in terms of two parts: the number on top is called the numerator and the number on the bottom is called the denominator. We can use the division method to solve this question. To get a decimal, simply divide the numerator 122 by the denominator 8:
122 (numerator) ÷ 8 (denominator) = 15.25
As a result, you get 15.25 as your answer when you convert 15 2/8 (or 122/8) to a decimal.
