Simplify the individual fractions before multiplying them together. Because a fraction is a ratio of numbers, you should make them as small as possible before doing any operations with them. For example, if multiplying 8/12 and 3/6, you should simplify 8/12 to 2/3 and 3/6 to 1/2.
Multiply the numerators together to get the numerator for the product; then multiply the denominators together to get the denominator for the product. So 2/3 multiplied by 1/2 becomes 2/6.
Simplify the product. Divide the numerator and denominator by the greatest common factor. So divide 2 by 2 and 6 by 2 to obtain 1/3.
