Multiplying Fractions

To multiply fractions, multiply the numerators and multiply the denominators. For fractions `a/b` and `c/d`, `(a/b)*(c/d)=(ac)/(bd)`. Practice!

Sometimes, it is helpful to multiply by the RECIPROCAL of a fraction. The reciprocal is just the fraction flipped over (or upside down). The product of a fraction and its reciprocal is = 1.

Sometimes, if you have a MIXED NUMBER, you need to convert the mixed number into an IMPROPER FRACTION.
