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 47 by the denominator 39:
47 (numerator) ÷ 39 (denominator) = 1.21
As a result, you get 1.21 as your answer when you convert 1 8/39 (or 47/39) to a decimal.
