The toy factory processes a batch of children's toys. The original plan is to process 1,500 per day, which can be completed in 60 days; the actual daily processing is 20% more than the original plan. How many days did it actually take to process this batch of toys? (Solve with ratio)
玩具厂加工一批儿童玩具，原计划每天加工1500个，60天可以完成；实际每天比原计划多加工20%．加工这批玩具实际用了多少天？(用比例解)
<gadget id="calculator">1_500 * 60</gadget>
<output>90_000</output>

<gadget id="calculator">20 / 100</gadget>
<output>1/5 = around 0.2</output>

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

<gadget id="calculator">1_500 + 300</gadget>
<output>1_800</output>

<gadget id="calculator">90_000 / 1_800</gadget>
<output>50</output>

<result>50</result>
