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 123 by the denominator 22:
123 (numerator) ÷ 22 (denominator) = 5.59
As a result, you get 5.59 as your answer when you convert 3 57/22 (or 123/22) to a decimal.
