The void ratio of a clay soil sample $\text{M}$ decreased from $0.575$ to $0.510$ when the applied pressure is increased from $\text{120 kPa}$ to $\text{180 kPa}$. For the same increment in pressure, the void ratio of another clay soil sample $\text{N}$ decreases from $0.600$ to $0.550$. If the ratio of hydraulic conductivity of sample $\text{M}$ to sample $\text{N}$ is $0.125$, then the ratio of coefficient of consolidation of sample $\text{M}$ to sample $\text{N } (\textit{round off to three decimal places}$) is __________________
