Math 8 – Students had a quiz on ratios today and they did pretty good. By far the biggest problem students have is determining what is being compared in a question. In the above question, students that struggled had a hard time figuring out what the ratio 2:3 referred to. Once this is figured out, the rest seems to go ok.  I think we ended summarizing that ratio problems involve three things: determining what is being compared, working out equivalent ratios, and then determining which is bigger.
