When an amount of water gets frozen its volume increases by 1/11 of the original volume. By what

part does the volume decrease then when the ice melts again?

If you have 1 volume unit ($\displaystyle u_V$) of water which freezes to ice you'll get $\displaystyle 1 u_V + \frac1{11} u_V=\frac{12}{11} u_V$

When the ice is melting to water obviously you'll get again $\displaystyle 1 u_V = \frac{11}{11} u_V$. That means the volume of the ice must decrease by $\displaystyle \frac1{12} u_V$
