一个工程队修一段公路，第一天修了全长的(2/5)，第二天修了剩下的(2/3)，第二天修了80米，这段公路全长多少千米？
<gadget id="calculator">2 / 5</gadget>
<output>2/5 = around 0.4</output>

<gadget id="calculator">1 - (2/5)</gadget>
<output>3/5 = around 0.6</output>

<gadget id="calculator">2 / 3</gadget>
<output>2/3 = around 0.666667</output>

<gadget id="calculator">(3/5) * (2/3)</gadget>
<output>2/5 = around 0.4</output>

<gadget id="calculator">80 / (2/5) / 1_000</gadget>
<output>1/5 = around 0.2</output>

<result>1/5 = around 0.2</result>
