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 138 by the denominator 22:
138 (numerator) ÷ 22 (denominator) = 6.27
As a result, you get 6.27 as your answer when you convert 6 6/22 (or 138/22) to a decimal.
