<gadget id="calculator">1 / 25</gadget>
<output>1/25 = around 0.04</output>

<gadget id="calculator">240 / (1/25)</gadget>
<output>6_000</output>

<gadget id="calculator">1 / 20</gadget>
<output>1/20 = around 0.05</output>

<gadget id="calculator">6_000 * (1/20)</gadget>
<output>300</output>

<result>300</result>
