Solving Multiplication And Division Fraction Equations

  1. 1. Solving Multiplication and Division Fraction Equations 12/9/2009
  2. 2. Note of Warning… <ul><li>All multiplication and division equations in this section may be treated as multiplication equations. Simply multiply both sides of the equation by the reciprocal and simplify as needed. </li></ul>
  3. 3. 2x = 1/3 <ul><li>Don’t forget…when you’re dividing fractions, you must flip the second fraction and multiply. </li></ul><ul><li>Multiply both sides by the reciprocal of 2 (1/2) </li></ul><ul><li>1/3 x ½ = 1/6 </li></ul><ul><li>x=1/6 </li></ul>
  4. 4. 5x/6 = 4 <ul><li>Multiply both sides by the reciprocal of 5/6 (6/5). </li></ul><ul><li>Make 4 a fraction by putting it over 1. </li></ul><ul><li>Multiply straight across and simplify! (top x top) 6x4 = 24; (bottom x bottom) 5x1=5 24/5 in simplest form is 4 and 4/5 </li></ul>
  5. 5. 5/6 = w/4 <ul><li>Multiply both sides by the reciprocal of ¼ (4/1) </li></ul><ul><li>Multiply straight across and simplify as needed. (top x top) 5x4=20; (bottom x bottom) 6x1=6 20/6 in simplest form is 3 and 1/3 </li></ul>
