In the given figure, two wheels P and Q are connected by a belt B. The radius of P is three times as that of Q. In case of same rotational kinetic energy, the ratio of rotational inertias $\displaystyle \left(\frac{I_1}{I_2}\right)$ will be $\displaystyle x: 1$. The value of $\displaystyle x$ will be \_\_\_\_.
