A $$\color{blue}{100}$$ g sample of methane hydrate, in the form known as clathrate structure II, $$(\ce{CH4})_x(\ce{H2O})_y$$ was burnt in excess oxygen in a sealed container. After the reaction had completed and the products had cooled, $$\color{blue}{116.92}$$ g of water was recovered from the container, and the gas, when shaken with excess lime water, gave $$\color{blue}{84.73}$$ g of $$\ce{CaCO3}$$.

The molar mass of the hydrate and $$\ce{CaCO3}$$ are $$\color{blue}{2835.18}$$ g/mol and $$\color{blue}{100.09}$$ g/mol, respectively.

Find $$\huge \lfloor \frac{y}{x} \rfloor$$.
