Dividing Fractions by Fractions
To Divide Fractions:
 Invert (i.e. turn over) the denominator fraction and multiply the fractions
 Multiply the numerators of the fractions
 Multiply the denominators of the fractions
 Place the product of the numerators over the product of the denominators
 Simplify the Fraction
Example: Divide 2/9 and 3/12
 Invert the denominator fraction and multiply (2/9 ÷ 3/12 = 2/9 * 12/3)
 Multiply the numerators (2*12=24)
 Multiply the denominators (9*3=27)
 Place the product of the numerators over the product of the denominators (24/27)
 Simplify the Fraction (24/27 = 8/9)

 The Easy Way. After inverting, it is often
simplest to "cancel" before doing the multiplication. Canceling is dividing one
factor of the numerator and one factor of the denominator by the same number.
 For example: 2/9 ÷ 3/12 = 2/9*12/3 = (2*12)/(9*3) = (2*4)/(3*3) = 8/9
