In a first order decomposition reaction, the time taken for the decomposition of reactant to one fourth and one eighth of its initial concentration are $\displaystyle \mathrm{t}_1$ and $\displaystyle \mathrm{t}_2(\mathrm{~s})$, respectively. The ratio $\displaystyle \mathrm{t}_1 / \mathrm{t}_2$ will be:
