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 27:
142 (numerator) ÷ 27 (denominator) = 5.26
As a result, you get 5.26 as your answer when you convert 2 88/27 (or 142/27) to a decimal.
