For a fraction, the difference between the numerator and the denominator is 27. If both the numerator and the denominator are reduced by 5 and simplified to (2/5), what is the original fraction?
一个分数，分子与分母的差是27，如果分子、分母同时减少5，化简为(2/5)，原分数是多少？
<gadget id="calculator">2 / 5</gadget>
<output>2/5 = around 0.4</output>

<gadget id="calculator">(2/5) * 27</gadget>
<output>54/5 = around 10.8</output>

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

<gadget id="calculator">(54/5) - 2</gadget>
<output>44/5 = around 8.8</output>

<gadget id="calculator">5 + (44/5)</gadget>
<output>69/5 = around 13.8</output>

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

<gadget id="calculator">(69/5) / (3/5)</gadget>
<output>23</output>

<gadget id="calculator">23 + 27</gadget>
<output>50</output>

<gadget id="calculator">(69/5) / (3/5) / 50</gadget>
<output>23/50 = around 0.46</output>

<result>23/50 = around 0.46</result>
