im not sure what you mean by rate base amount....

but answering the question itself.

to calculate a percentage, generally you would do

I think it is this: I keep 2nd guessing myself!

RATE= 8

BASE=25

AMOUNT=% OF STUDENTS RECEIVING A'S

I think it is vice-versa, though, as I think "rate" is kinda short of "ratio", which is the percentage itself, which is 32% or 8:25. Not sure about the base and amount, though.

RATE=32

BASE=25

AMOUNT=NUMBER OF STUDENTS RECEIVING A'S=8

I corrected the mistake in rate.
