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.

Dividing FractionsEssential Understanding: • To divide a fraction by a fraction, begin by finding the reciprocal of the divisor (flip
the second fraction). Then simply multiply numerator by numerator and denominator by denominator. In other word, Keep Change Flip
