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 57 by the denominator 17:
57 (numerator) ÷ 17 (denominator) = 3.35
As a result, you get 3.35 as your answer when you convert 1 40/17 (or 57/17) to a decimal.
