1/23/2008 Pre Algebra - Solving Equations Involving Fractions

Today we put our work with fractions to use in solving equations.  In order to solve an equation with a fraction coefficient (ie 2/3x = 8), you must multiply both sides of the equation by the reciprocal of the fraction (3/2 for our example).  We did some example problems on the board together, students did some on their own on a worksheet, then did a problem as an in class assessment.
