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 80 by the denominator 20:
80 (numerator) ÷ 20 (denominator) = 4
As a result, you get 4 as your answer when you convert 80/20 to a decimal.
