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 89 by the denominator 40:
89 (numerator) ÷ 40 (denominator) = 2.23
As a result, you get 2.23 as your answer when you convert 2 9/40 (or 89/40) to a decimal.
