Multiplying Rational Numbers

• To multiply fractions, multiply the numerators then multiply the denominators; lastly simplify if possible.
• You can use cross simplification to make multiplying fractions and simplifying products of fractions a lot easier.
• To raise a fraction to a power, pay careful attention to the location of the exponent. Sometimes you will be repeatedly multiplying both the numerator and denominator. Sometimes you will only be multiplying the numerator or denominator. Finally, sometimes you may not be repeatedly multiplying the negative sign.
