Multiplying Fractions
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.

Dividing Fractions
Essential Understanding: • To divide a fraction by a fraction, simply flip the
second fraction and multiply. • To divide a fraction by a whole number or a mixed
number, change the number to an improper fraction. Then, flip the second fraction and multiply.
