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 128:
138 (numerator) ÷ 128 (denominator) = 1.08
As a result, you get 1.08 as your answer when you convert 138/128 to a decimal.
