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 23 by the denominator 20:
23 (numerator) ÷ 20 (denominator) = 1.15
As a result, you get 1.15 as your answer when you convert 1 3/20 (or 23/20) to a decimal.
