用简便算法计算：(1/15)*((1/3)+(1/12))
<gadget id="calculator">1 / 15</gadget>
<output>1/15 = around 0.066667</output>

<gadget id="calculator">1 / 3</gadget>
<output>1/3 = around 0.333333</output>

<gadget id="calculator">1 / 12</gadget>
<output>1/12 = around 0.083333</output>

<gadget id="calculator">(1/3) + (1/12)</gadget>
<output>5/12 = around 0.416667</output>

<gadget id="calculator">(1/15) * (5/12)</gadget>
<output>1/36 = around 0.027778</output>

<result>1/36 = around 0.027778</result>
