One method to convert 181/4 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 181 by the denominator 4:
181 (numerator) ÷ 4 (denominator) = 45.25
And there you go! We got 45.25 as the answer when you convert 45 1/4 (or 181/4) to a decimal.
