Rotational Inertia of a Pentagon

Five identical point masses form a regular pentagon with side length $s$. Let $I_1$ be the rotational inertia of the system about an axis passing through one vertex and perpendicular to the plane of the pentagon. Let $I_2$ be the rotational inertia about an axis passing through the center of the pentagon and perpendicular to its plane. What is the ratio $I_1/I_2$?
