(Multiplying and Dividing Fractions)

  Find common denominator  Make sure you have the lowest common denominator to make your job easier in the end!  Add top numbers Adding Fraction Review

  Find Common Denominator  Subtract first number from second number Subtracting Fraction Review

  Multiply the two top numbers  The top numbers in a fraction are referred to as the numerator Multiply Fractions

  Multiply the bottom numbers  The bottom numbers are referred to as the denominators Multiply Fractions

  Now you can multiply any numbers  Samples will make multiplying easier  Try  ½ x ¾  5/8 x 65/23 Multiply Fractions

  Turn the second fraction upside down  Upside down fractions are called the reciprocal Dividing Fractions

  Multiply the first fraction by the reciprocal  Multiplying fractions is needed to divide fractions! Divide Fractions

  Simplify fraction  Examples  4/8=1/2  200/100=2 Divide Fractions

  Again, practice makes perfect  Try to divide these numbers  3 / (2/3)  (4/10 ) / (30/34)  You are now a master divider  Master of (Dividing) Practice
