Multiplying Fractions(Review)

Essential Understanding: •To multiply a fraction by a fraction, you simply multiply the numerator by numerator, then the denominator by denominator. •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 then 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
