Two methods: (1) Convert the mixed fractions to improper fractions first. This is generally the easier method. (2) Use the distributive property. For example, 2 x 3 1/3 = 2 x (3 + 1/3) = 2 x 3 + 2 x 1/3 = 6 + 2/3 = 6 2/3.

if you have mixed numbers you make them into improper fractions before you multiply
Mixed numbers cannot be turned into proper fractions, but they can be made into improper fractions by multiplying the integer (# on the side) by the denominator (bottom), and then adding that number to the numerator (top).
First you change them into improper fractions. Then you multiply the numerator and the denamanator straight across. ;)
You convert them both to improper fractions by multiplying the denominators by the whole number and then adding the numerator to it. This number goes in the numerator and the denominator stays the same. Then you do this for the other fraction, making sure that the denominators of each fraction are equivalent. Then add the fractions as normal.
Because common denominators allow adding and subtracting of numerators. Improper fractions also have simplified rules over mixed numbers when performing multiplication and division.
