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 144 by the denominator 30:
144 (numerator) ÷ 30 (denominator) = 4.8
As a result, you get 4.8 as your answer when you convert 3 54/30 (or 144/30) to a decimal.
