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 40 by the denominator 2:
40 (numerator) ÷ 2 (denominator) = 20
As a result, you get 20 as your answer when you convert 40/2 to a decimal.
