One method to convert 45/30 to a decimal is by using the division method. Before we move ahead to the method, here is a quick recap on fractions: A fraction is a number representation that is broken down into two parts - the number on top is called the numerator, and the number on the bottom is called the denominator. To get a decimal using the division method, simply divide the numerator 45 by the denominator 30:
45 (numerator) ÷ 30 (denominator) = 1.5
And there you go! We got 1.5 as the answer when you convert 1 15/30 (or 45/30) to a decimal.
