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 319 by the denominator 321:
319 (numerator) ÷ 321 (denominator) = 0.99
As a result, you get 0.99 as your answer when you convert 319/321 to a decimal.
