Multiplying Fractions and Mixed Numbers

Topics for Today:

We are moving right along with fraction operations. Today we discussed multiplying fractions and mixed numbers.  There is no need for a common denominator when multiplying.  We do have to convert any mixed numbers to improper fractions before we can perform the multiplication.  Because multiplying numbers can make our answers get very big, very fast, we first want to divide out common factors in the numerator and denominator before we multiply.
