Ratios and the Internet

Now he's working on ratios. The first worksheet came home tonight and Christopher asked if I would check his work.

OK, the first part of each of the six questions was easy -- what's the ratio of something to the total. One was ratio of completed passes to total thrown. Easy, got it.

Then, the second part of the questions raised the ante -- what's the ratio of completed passes to incomplete. Maybe I overthought it,but we used the trusty Internet -- a great math site on ratios -- to instruct us. Aaahh, we got it.

What would we do without the Internet? Maybe the bigger question is where are the notes on ratios from Christopher's math class?
