Under normal circumstances, the mass of ice of equal volume is less than the mass of water (1/11). Now a piece of ice weighs 9 kg. If there is a bucket of water equal in volume to the volume of the ice, how much does the bucket of water weigh? (solution by equation)
在通常情况下，体积相等的冰的质量比水的质量少(1/11)，现在一块重9千克的冰，如果有一桶水的体积和这块冰的体积相等，这桶水有多重？(用方程解)
<gadget id="calculator">1 / 11</gadget>
<output>1/11 = around 0.090909</output>

<gadget id="calculator">1 - (1/11)</gadget>
<output>10/11 = around 0.909091</output>

<gadget id="calculator">9 / (10/11)</gadget>
<output>99/10 = around 9.9</output>

<result>99/10 = around 9.9</result>
