To multiply fractions, you do NOT need to find a common denominator (LCD- see vocab), but you must change any mixed number to an improper fractions (see post about this topic). To start, cross factor if possible (see post below), then multiply the denominators to get the BOTTOM number of the product, then multiply the numerators to get the TOP number of the product. Then simplify, and if you have an improper fraction (see vocab), then you change it to a mixed number (see vocab AGAIN)
Ex.: 3/7 x 4/8
first, you multiply 8 x 7 = 56,
then you multiply 3 x 4= 12.
The product is 12/56. Then simplify to get: 6/28
