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 45 by the denominator 2:
45 (numerator) ÷ 2 (denominator) = 22.5
As a result, you get 22.5 as your answer when you convert 11 23/2 (or 45/2) to a decimal.
