<output>2/3 = around 0.666667</output>

<gadget id="calculator">2 / 9</gadget>
<output>2/9 = around 0.222222</output>

<gadget id="calculator">(2/3) + (2/9)</gadget>
<output>8/9 = around 0.888889</output>

<gadget id="calculator">3 / 4</gadget>
<output>3/4 = around 0.75</output>

<gadget id="calculator">(3/4) / 2</gadget>
<output>3/8 = around 0.375</output>

<gadget id="calculator">(8/9) * (3/8)</gadget>
<output>1/3 = around 0.333333</output>

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