Remember in class I mentioned that it is really helpful to have a few fractions and decimal equivalents memorized.  Having a handful of these memorized will help you with your fluency to convert among the various forms of a number.

Take a look at the following tables.  Look for patterns.  You might notice that you don't have to memorize the whole table but only one fraction for a given denominator.  For example, if you know that every eighth is equal to 0.125, you can determine 3/8 by adding 0.125 to itself three times.

Notice that the ninths are missing from both tables.  Just remember that the numerator is the decimal repeated.  So 4/9 is equal to .4444...
