李师傅加工一批零件，计划每天加工250个，6天完成任务，实际每天比计划多加工(1/5)，实际几天完成任务？(用比例解)
<gadget id="calculator">250 * 6</gadget>
<output>1_500</output>

<gadget id="calculator">1 / 5</gadget>
<output>1/5 = around 0.2</output>

<gadget id="calculator">250 * (1/5)</gadget>
<output>50</output>

<gadget id="calculator">250 + 50</gadget>
<output>300</output>

<gadget id="calculator">1_500 / 300</gadget>
<output>5</output>
