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 74 by the denominator 18:
74 (numerator) ÷ 18 (denominator) = 4.11
As a result, you get 4.11 as your answer when you convert 3 20/18 (or 74/18) to a decimal.
