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 86 by the denominator 3:
86 (numerator) ÷ 3 (denominator) = 28.67
As a result, you get 28.67 as your answer when you convert 11 53/3 (or 86/3) to a decimal.
