Subject: [Math4u] Re: 4 situations
As usual I disagree with you.
First website I found
http://www.mathleag ue.com/help/ ratio/ratio. htm
gives ratios with different units, defines proportion, and says rate
involves time.
Second website I found
http://www.math. com/school/ subject1/ lessons/S1U2L1GL .html
gives ratios with different units
Third website I found
http://www.purplema th.com/modules/ ratio.htm
gives ratios with different units
The "Understanding" of others is often made up nonsense. What is
taught in school is not reliable. Let's get some websites to back up
information.

Brian

When you compare two quantities of different units you have a RATE.
That is my understanding. Others may clarify it further.
