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 20:
122 (numerator) ÷ 20 (denominator) = 6.1
As a result, you get 6.1 as your answer when you convert 6 2/20 (or 122/20) to a decimal.
