Question

Describe the similarities and differences between the percent proportion and the percent equation.

Answer 1

In this case I think you'd probably be better off looking up "percent proportion" and "percent equation" yourself, e. g., using Google.

I've dealt with math most of my life (I'm 72), but have yet to encounter your "percent proportion" or "percent equation" until now.

Perhaps if you were to share some specific problems involving proportions and percents / percentages, it'd be easier for me and others to understand what you're looking for.
