How do you multiply improper fractions?
Multiplying improper fractions is just like multiplying proper fractions. You multiply the numerators (top number) of each fraction to come up with the numerator of the answer. The you multiply the denominators (bottom number) of both numbers to get the denominator of the answer.EX: 8/3 X 9/5= 72/15 or 24/5 (reduced)The next step in the equation is taking the improper fraction and converting it to a mixed number. You do this by dividing the numerator by the denominator. The whole number of the quotient becomes the whole number in the fraction, and the remainder becomes the numerator, which is over the denominator of the improper fractionEX: 24/5= 4 and 4/5; 24 divided by 5 = 4 with a remainder of 4.you just multiply as you would an number
