I drank a bucket of water in three days, drank 4 kilograms on the first day, drank the rest (5/12) on the second day, and drank half of the bucket on the third day. How many kilograms is this bucket of water?
一桶水三天喝完，第一天喝了4千克，第二天喝了余下的(5/12)，第三天正好喝了半桶，这桶水有多少千克？
<gadget id="calculator">5 / 3</gadget>
<output>5/3 = around 1.666667</output>

<gadget id="calculator">4 - (5/3)</gadget>
<output>7/3 = around 2.333333</output>

<gadget id="calculator">5 / 12</gadget>
<output>5/12 = around 0.416667</output>

<gadget id="calculator">1 / 2</gadget>
<output>1/2 = around 0.5</output>

<gadget id="calculator">1 - (5/12) - (1/2)</gadget>
<output>1/12 = around 0.083333</output>

<gadget id="calculator">(7/3) / (1/12)</gadget>
<output>28</output>
