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 80 by the denominator 23:
80 (numerator) ÷ 23 (denominator) = 3.48
As a result, you get 3.48 as your answer when you convert 1 57/23 (or 80/23) to a decimal.
