把一根铁丝截成两段，第一段长(3/5)米，第二段占全长的(3/5)，那么第二段比第一段长多少米．
<gadget id="calculator">3 / 5</gadget>
<output>3/5 = around 0.6</output>

<gadget id="calculator">1 - (3/5)</gadget>
<output>2/5 = around 0.4</output>

<gadget id="calculator">(3/5) / (2/5)</gadget>
<output>3/2 = around 1.5</output>

<gadget id="calculator">(3/2) * (3/5)</gadget>
<output>9/10 = around 0.9</output>

<gadget id="calculator">(9/10) - (3/5)</gadget>
<output>3/10 = around 0.3</output>

<result>3/10 = around 0.3</result>
