SOLVING EQUATIONS WITH FRACTIONS
NetScape 3.0+ or I.E. 4.0+ needed
Suggestions for this self exam:
[A] Study text section 4.5 , but then keep your book closed during this entire test
[B] Enter your answers in the boxes provided. Check them when you've finished.
[C]
 Remember the general rules: ab = acbc and also ad + bd = a + bd
[D]
 In many cases, the most effective way to solve an equation containing fractions is to multiply both sides of the equation by the least common denominator, or LCD of all fractions in the equation. If this LCD contains the variable of the equation, this step may introduce roots that will not check in the original equation. Thus, CHECK ALL ROOTS
