One method to convert 161/2 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 161 by the denominator 2:
161 (numerator) ÷ 2 (denominator) = 80.5
And there you go! We got 80.5 as the answer when you convert 80 1/2 (or 161/2) to a decimal.
