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 91 by the denominator 18:
91 (numerator) ÷ 18 (denominator) = 5.06
As a result, you get 5.06 as your answer when you convert 1 73/18 (or 91/18) to a decimal.
