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 4:
40 (numerator) ÷ 4 (denominator) = 10
As a result, you get 10 as your answer when you convert 5 20/4 (or 40/4) to a decimal.
