To test the germination rate of a batch of seeds, 80 seeds were taken for the first time, and 60 seeds germinated, and 20 seeds were taken for the second time, and all germinated. What is the germination rate of this batch of seeds?
实验一批种子的发芽率，第一次取80粒，有60粒发芽，第二次取20粒，全部发芽．这批种子的发芽率是多少．
<gadget id="calculator">60 + 20</gadget>
<output>80</output>

<gadget id="calculator">80 + 20</gadget>
<output>100</output>

<gadget id="calculator">80 / 100</gadget>
<output>4/5 = around 0.8</output>

<gadget id="calculator">100 / 100</gadget>
<output>1</output>

<gadget id="calculator">(4/5) * 1</gadget>
<output>4/5 = around 0.8</output>

<result>4/5 = around 0.8</result>
