**Reiny**, Friday, May 6, 2011 at 5:55pmJust saw your other post.

What don't you understand?

I will do the quarterly rate problem.

Let the effective annual rate be i

so the interest factor will be (1+i)^1 for one year

(you should know the (1+i)^n part)

you want this to be equal to a rate of 6% per annum compounded quarterly , or

a rate of .06/4 or .015 per quarter, with n = 4

so (1+i)^1 = (1+.015)^4

1+i = 1.015^4

1+i = 1.06136551

i = .06136551

you wanted 2 decimals, so

the effective annual rate is 6.14 %

see if you can the others the same way.
