Final answer:
The ratio of the employer's contribution to the employee's contribution is 0.48.
Step-by-step explanation:
The ratio of the employer's contribution to the employee's contribution is determined by comparing the amount paid by each party. In this case, the employee pays $625, while the employer pays $300. To find the ratio, divide the employer's contribution by the employee's contribution:
Ratio = Employer's contribution / Employee's contribution
Ratio = $300 / $625 = 0.48
Therefore, the ratio of the employer's contribution to the employee's contribution is 0.48.
