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 38 by the denominator 20:
38 (numerator) ÷ 20 (denominator) = 1.9
As a result, you get 1.9 as your answer when you convert 1 18/20 (or 38/20) to a decimal.
