<output>1/4 = around 0.25</output>

<gadget id="calculator">7 / 8</gadget>
<output>7/8 = around 0.875</output>

<gadget id="calculator">(1/4) - (7/8)</gadget>
<output>-5/8 = around -0.625</output>

<gadget id="calculator">1 + (-5/8)</gadget>
<output>3/8 = around 0.375</output>

<gadget id="calculator">9.6 / (3/8)</gadget>
<output>25.6</output>

<result>25.6</result>
