An engineering team built a road with a length of 1,000 kilometers, completed 1/3 of the total length in the first week, completed 1/4 of the total length in the second week and third week, and left a fraction of the total length How long has it been repaired?
某工程队修一条长1000千米的公路，第一周完成了全长的1/3，第二周和第三周各完成了全长的1/4，还剩下全长的几分之几没修？
<gadget id="calculator">1 / 3</gadget>
<output>1/3 = around 0.333333</output>

<gadget id="calculator">1 / 4</gadget>
<output>1/4 = around 0.25</output>

<gadget id="calculator">1 - (1/3) - (1/4) - (1/4)</gadget>
<output>1/6 = around 0.166667</output>

<result>1/6 = around 0.166667</result>
