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 88 by the denominator 21:
88 (numerator) ÷ 21 (denominator) = 4.19
As a result, you get 4.19 as your answer when you convert 4 4/21 (or 88/21) to a decimal.
