一批种子做发芽试验，第一次取100粒，有75粒发芽；第二次取25粒，全部发芽．这批种子的发芽率是多少
<gadget id="calculator">75 + 25</gadget>
<output>100</output>

<gadget id="calculator">100 + 25</gadget>
<output>125</output>

<gadget id="calculator">100 / 125</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>
