Ratios and Proportions

I hope that your getting a little bit more comfortable with ratios
This next link is not khanacademy  - It links you to a ratio / proportion tutorial.  Please follow the tutorial through the part where you define the words - the tutorial will continue after that and you are welcome to continue but I am not requiring it.  You can use a caluculator on the practice part if you need it.
