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 55 by the denominator 3:
55 (numerator) ÷ 3 (denominator) = 18.33
As a result, you get 18.33 as your answer when you convert 18 1/3 (or 55/3) to a decimal.
