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 42 by the denominator 11:
42 (numerator) ÷ 11 (denominator) = 3.82
As a result, you get 3.82 as your answer when you convert 3 9/11 (or 42/11) to a decimal.
