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 66 by the denominator 40:
66 (numerator) ÷ 40 (denominator) = 1.65
As a result, you get 1.65 as your answer when you convert 66/40 to a decimal.
