一个分数，分子和分母的和是62，如果分子和分母都减去25，得到的分数约简后是(1/5)，原来这个分数是多少．
<gadget id="calculator">1 / 5</gadget>
<output>1/5 = around 0.2</output>

<gadget id="calculator">(1/5) * 62</gadget>
<output>62/5 = around 12.4</output>

<gadget id="calculator">(1/5) * 25</gadget>
<output>5</output>

<gadget id="calculator">(62/5) - 5</gadget>
<output>37/5 = around 7.4</output>

<gadget id="calculator">25 + (37/5)</gadget>
<output>162/5 = around 32.4</output>

<gadget id="calculator">1 + (1/5)</gadget>
<output>6/5 = around 1.2</output>

<gadget id="calculator">(162/5) / (6/5)</gadget>
<output>27</output>

<gadget id="calculator">62 - 27</gadget>
<output>35</output>

<gadget id="calculator">(162/5) / (6/5) / 35</gadget>
<output>27/35 = around 0.771429</output>

<result>27/35 = around 0.771429</result>
