on a very basic level decimals are just parts of numbers, like fractions of a whole. with each place to the right being 10 times less than what it was previously eg 0.1 is ten times less than 1 and 0.01 is ten times less than 0.1. this also makes 0.01, 100 times less than 1.
hope that helped a little but check out the sites above as well.
