FRACTIONS Review of Introductory Mathematics Step 2: Multiplication of division fractions equals 1. = 3 8 7 6 1 Step 3: Multiplication of numerators and denominators yields: 3 8 7 6 21 48 The second method for dividing fractions is really a short cut to the first method.  When dividing one fraction by another, first invert the divisor fraction and then multiply. Example: 4 5 2 9 Solution: Step 1: Invert the divisor fraction to . 2 9 9 2 Step 2: Multiply the dividend fraction, , by the inverted fraction . 4 5 9 2 4 5 9 2 36 10 Step   3: Reduce fraction to lowest terms. 36 2 10 2 18 5 3³ 5 Division  of  mixed  numbers  may  be  accomplished  by  changing  the  mixed  number  into  an improper fraction (a/b), inverting the divisor, and proceeding as in multiplication.
