First order decomposition, $\mathrm{A}(\mathrm{g})\to$ product has half life 80 min. and ${\left(\frac{1}{4}\right)}^{\text{th }}$ completion time ${\mathrm{t}}_1$ min. Another first order decomposition, $\mathrm{B}(\mathrm{g})\to$ product has half life 10 min . and ${\left(\frac{3}{4}\right)}^{\text{th }}$ completion time ${\mathrm{t}}_2$ min. The value of $\left(\frac{t_2}{t_1}\right)$ is $\_\_\_\_$ . $(\ln 2=0.7$ and $\ln 3=1.1)$
