<output>1/3 = around 0.333333</output>

<gadget id="calculator">(1/3) * 100</gadget>
<output>100/3 = around 33.333333</output>

<gadget id="calculator">(1/3) * 6</gadget>
<output>2</output>

<gadget id="calculator">(100/3) - 2</gadget>
<output>94/3 = around 31.333333</output>

<gadget id="calculator">6 + (94/3)</gadget>
<output>112/3 = around 37.333333</output>

<gadget id="calculator">1 + (1/3)</gadget>
<output>4/3 = around 1.333333</output>

<gadget id="calculator">(112/3) / (4/3)</gadget>
<output>28</output>

<gadget id="calculator">100 - 28</gadget>
<output>72</output>

<gadget id="calculator">(112/3) / (4/3) / 72</gadget>
<output>7/18 = around 0.388889</output>

<result>7/18 = around 0.388889</result>
