You make 40 into 100 by multiplying it by 2.5.
Which means its out of 100, which means you can use percentage.
Then you multiply 32 by 2.5, which makes it 80, So you got 80%.

ok...
considering that percentage is generally (ie. always) represented as between 0 and 100, 40 is quite an easy number...
let a equal number of correct answers...
let b equal 100
let c equal the percentage
2.5a/b*100 = c
that is: 2.5*a (80) / b(100) *100 = c (80)
