LSU math problem

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?

$V_i \rightarrow 1.1 V_w$

$1.1 V_w \rightarrow V_w$

$\dfrac{1.1 V_w - V_w}{1.1 V_w} = \dfrac{0.1}{1.1} = \dfrac {1}{11}$
Thanks from AshBox
