Hi everyone, I was searching puzzles of geometry questions. Can any one answer me for this one. Water when freezing (and turning into ice) enlarges its volume by a factor of 1/10. By what factor will the volume of ice decrease when it is melted?

$V_i \rightarrow 1.1 V_w$ $1.1 V_w \rightarrow V_w$ $\dfrac{1.1 V_w  V_w}{1.1 V_w} = \dfrac{0.1}{1.1} = \dfrac {1}{11}$
