A "popcorn process" refers to changing a mixed number to animproper fraction, e.g. 1 1/2 to 3/2.It is so named because of the three lobes of a popped kernel, ananalog to the whole number, numerator, and denominator of a mixednumber.The reverse process, changing an improper fraction to a mixednumber, uses division of the numerator by the denominator, with anyremainder left over the original denominator.Examples :- to change 3 4/5 to an improper fraction, multiply 3 times thedenominator and add to 4.3 4/5 = 15/5 + 4/5 = 19/5- to change 19/5 to a mixed number, divide the 19 by 5, yielding3 with a remainder of 4.19/5 = 15/5 + 4/5 = 3 4/5- for fractions not in simplest form, divide by the GreatestCommon Factor.39/9 = 36/9 + 3/9 = 4 3/9 = 4 1/3
