A fraction is usually split into two parts: the first part is the number on top, called the numerator; and the second part is the number on the bottom, called the denominator. These are both separated by a line called the “divisor line”. We can use the division method help to solve this question: to get a decimal, simply divide the numerator 144 by the denominator 32 (which you can enter in any calculator):
144 (numerator) ÷ 32 (denominator) = 4.5
And finally, you get 4.5 as your answer when you convert 2 80/32 (or 144/32) to a decimal.
