This page lets you practice your percentage calculations. The problems
are randomly generated when you press the "New Problem" button. Enter your answer in the empty
square and press "Check Answer". The results are displayed in the second table which will
tell you whether you got the correct answer or not and keeps a running total of your score.
If you get a question wrong, you can redo and recheck your answer. Getting new problems is just a mater of
pressing the "New Problem" button at any time.
