thanks.

divide both sides by p:
1+rt=a/p
subtract 1 from each side:
rt=a/p-1
divide both sides by t:
r=(a/p-1)/t
which you could simplify to:
r=(a-p)/(pt)

[ ( a / p ) - 1 ] / t

at/p-1=r I think
or a/pt-1=r
or a/p/t-1=r
I'm half asleep, but I think it's the second one.

Interest formula....if i'm not mistaken....
a=p(1+rt)
a/p=1+rt
(a/p)-1= rt
((a/p)-1)/t=r

a/p = 1 + rt
[(a/p) - 1] = rt
r = [(a/p) - 1] / t
= (a - p) / (pt)

a=p(1+rt) : distribute p by multiplying it to the 1 and the rt
_____________
a=p+prt : then subtract the p from both sides
_____________
a-p=prt : then divide the p and t from prt from both sides
_____________
a-p/pt=r <---answer
