Suggestions for this self exam:
[A] Study text section 4.4 , 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]
 A complex fraction is a fraction whose numerator and/or denominator contain fractions, such as in all problems below, and at the right: (¼)(¾) Our task here is to re-write a complex fraction as a simple fraction, whose numerator and denominator both contain no fractions. We may also want to reduce the simplified fraction: that is, cancel equal factors of numerator and denominator.
