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 135 by the denominator 45:
135 (numerator) ÷ 45 (denominator) = 3
As a result, you get 3 as your answer when you convert 2 45/45 (or 135/45) to a decimal.
