某工程队对益阳市资江大堤进行防洪加固，27天完成了工程的45%，按照这样的速度，完成余下的工程队还需要多少天？(用比例解)
<gadget id="calculator">45 / 100</gadget>
<output>9/20 = around 0.45</output>

<gadget id="calculator">(9/20) * 27</gadget>
<output>243/20 = around 12.15</output>

<gadget id="calculator">27 - (243/20)</gadget>
<output>297/20 = around 14.85</output>

<gadget id="calculator">(297/20) / (9/20)</gadget>
<output>33</output>

<result>33</result>
