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 142 by the denominator 57:
142 (numerator) ÷ 57 (denominator) = 2.49
As a result, you get 2.49 as your answer when you convert 142/57 to a decimal.
