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 20 by the denominator 17:
20 (numerator) ÷ 17 (denominator) = 1.18
As a result, you get 1.18 as your answer when you convert 1 3/17 (or 20/17) to a decimal.
