Multiplying Fractions(Review)

Essential Understanding: • To multiply a fraction by a fraction, you simply

multiply the numerators, then the denominators. • To multiply a fraction by a whole number or a mixed

number, you must first change the number to an improper fraction. Then, multiply the numerators and the denominators.

• Write each product in simplest form.
