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 126 by the denominator 27:
126 (numerator) ÷ 27 (denominator) = 4.67
As a result, you get 4.67 as your answer when you convert 3 45/27 (or 126/27) to a decimal.
