Question 99938
percent problems are expressed in terms of amount, base and rate
{{{amount=(base)(rate)}}}


RATE is the percent value
In this problem we are looking for the rate


BASE is the number to which the rate is applied. 
To identify base ask yourself percent of what?
In this problem we are asked what percent of the students received A's
So the base is the total number of students (25)

 
AMOUNT is what part of the whole is being compared to the base
the whole is the total number of students (25)
the amount is 8 because that is the number of students that received an A


{{{amount=(base)(rate)}}}
{{{8=(25)(rate)}}}
{{{8/25=rate}}}
{{{.32=rate}}}
to express as a percent just multiply by 100
32%
