已知一个分数的分子与分母的和为25，如分子缩小2倍，分母减少1，则等于(1/4)，这个分数是多少．
<gadget id="calculator">1 / 4</gadget>
<output>1/4 = around 0.25</output>

<gadget id="calculator">(1/4) * 25</gadget>
<output>25/4 = around 6.25</output>

<gadget id="calculator">(25/4) - (1/4)</gadget>
<output>6</output>

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

<gadget id="calculator">(1/2) + (1/4)</gadget>
<output>3/4 = around 0.75</output>

<gadget id="calculator">6 / (3/4)</gadget>
<output>8</output>

<gadget id="calculator">25 - 8</gadget>
<output>17</output>

<gadget id="calculator">6 / (3/4) / 17</gadget>
<output>8/17 = around 0.470588</output>

<result>8/17 = around 0.470588</result>
