一个工程队修一条公路，第一天修了60米，第二天修了剩下的(2/7)，这时已修的长度和未修的长度相等，这条公路全长多少米．
<gadget id="calculator">2 / 7</gadget>
<output>2/7 = around 0.285714</output>

<gadget id="calculator">1 - (2/7) - (2/7)</gadget>
<output>3/7 = around 0.428571</output>

<gadget id="calculator">60 / (3/7)</gadget>
<output>140</output>

<gadget id="calculator">140 + 60</gadget>
<output>200</output>

<result>200</result>
