Subject: teaching percents

	Another good way to teach percentages is the same thing that Jamie
said up above, but I learned it like this:

    fifty five percent of 60 is what?

  55        x 
------ = ------- 
 100        60

Then, you cross multiply

100x = 3300

And divide:

100x       3300
----   &   ---- 
100        100

So, x=33.  33 is 55% of 60.
