Stock Y has a beta of 1.05 and an expected return of 15.55 percent. Stock Z has a beta of .90 and an expected return of 6 percent. If the risk-free rate is 4.0 percent and the market risk premium is 8.8 percent, what are the reward-to-risk ratios of Y and Z? (Do not round intermediate calculations. Round your answers to 4 decimal places.)

Reward to risk ratio for stock Y:

= (15.55%-4%)1.05

= 11

Reward to risk ratio for stock Z:

= (6%-4%)0.9

= 2.22

Was told this was the answer but it is not correct!
