– to multiply fraction, multiply the numerators and then multiply the denominators. Then reduce to lowest terms if necessary.

ex: 2/3 x 4/6= 2 x 4=8

3 x 6=18

the answer is 8/18. then you need to reduce the answer (by dividing) 8/18= 4/9

– to divide fraction, we multiply the first fraction by the reciprocal (up side down) of the second fraction.

ex: 2/3 / 4/6= 2/3 x 6/4= 12/12 or 1

– to subtract or add fraction, we find the least common denominator than add or subtract the fraction normally

ex: 2/3-4/6= 4/6-4/6=0

ex:2/3+4/6= 4/6+4/6=8/6 or 4/3.

Hope this help. If you are still having problem, you should buy the cliffs quick review. It’s really good for 9.99 dollars.

or if you can, simplify the fractions before you multiply them
