parts factory originally planned to send 20 people to complete an assembly task, and it would be completed in 24 days. Due to work needs, it actually sent 30 people. Assuming that the work efficiency of these people is the same, the task can be completed in a few days.
某配件工厂原计划派20人完成一项装配任务，24天完成，因为工作需要，实际派了30人，假设这些人的工作效率相同，实际几天可以完成任务．
<gadget id="calculator">24 / 30</gadget>
<output>4/5 = around 0.8</output>

<gadget id="calculator">20 * (4/5)</gadget>
<output>16</output>

<result>16</result>
