在新农村建设中，某工程队要铺一条20千米的乡村公路，第一周铺了全长的(1/8)，第二周铺了全长的(3/16)，第二周比第一周多铺多少千米？
<gadget id="calculator">3 / 16</gadget>
<output>3/16 = around 0.1875</output>

<gadget id="calculator">1 / 8</gadget>
<output>1/8 = around 0.125</output>

<gadget id="calculator">(3/16) - (1/8)</gadget>
<output>1/16 = around 0.0625</output>

<gadget id="calculator">20 * (1/16)</gadget>
<output>5/4 = around 1.25</output>

<result>5/4 = around 1.25</result>
