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 140 by the denominator 45:
140 (numerator) ÷ 45 (denominator) = 3.11
As a result, you get 3.11 as your answer when you convert 3 5/45 (or 140/45) to a decimal.
