a) Effective monthly interest rate = (1 + effective quarterly interest rate)^(1/4) - 1
Effective monthly interest rate = (1 + 0.0325)^(1/3) - 1
Effective monthly interest rate = 0.0107180464
Effective monthly interest rate = 1.07180464%
Effective monthly interest rate = 1.072%
b) Effective quarterly rate = (1 + effective annual rate)^(3/12) - 1
Effective quarterly rate = (1 + 0.092)^(1/4) - 1
Effective quarterly rate = 0.02224656429
The nominal interest rate compounded quarterly = 0.02224656429 * 4
The nominal interest rate compounded quarterly = 0.08898625716
The nominal interest rate compounded quarterly = 8.898625716%
The nominal interest rate compounded quarterly = 8.90%
