Same type of question. 
Just 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. 
Okay i think i understand.
annually: 6%
semiannually: 6.09%
quarterly: 6.14%
monthly: 6.17%
