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 82 by the denominator 21:
82 (numerator) ÷ 21 (denominator) = 3.9
As a result, you get 3.9 as your answer when you convert 82/21 to a decimal.
