Why does the explanation say that a "perfect fifth" is a factor of 3/2 when it seems like the passage was saying that a perfect fifth is 2/3. Can you please explain what it is that I'm missing here.

I attached the given equation.

I might just be mixing up the terminology. Please help.

The fundamental frequency of each string is 2/3 that of the next higher frequency string, so if you're going to the HIGHER frequency string, the latter string will be a bigger number (which is why you multiply by the factor of 3/2) I think
