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 90 by the denominator 29:
90 (numerator) ÷ 29 (denominator) = 3.1
As a result, you get 3.1 as your answer when you convert 3 3/29 (or 90/29) to a decimal.
