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 17:
90 (numerator) ÷ 17 (denominator) = 5.29
As a result, you get 5.29 as your answer when you convert 5 5/17 (or 90/17) to a decimal.
