<gadget id="calculator">76 / 100</gadget>
<output>19/25 = around 0.76</output>

<gadget id="calculator">100 * (19/25)</gadget>
<output>76</output>

<gadget id="calculator">80 / 100</gadget>
<output>4/5 = around 0.8</output>

<gadget id="calculator">1 - (4/5)</gadget>
<output>1/5 = around 0.2</output>

<gadget id="calculator">100 * (1/5)</gadget>
<output>20</output>

<gadget id="calculator">85 / 100</gadget>
<output>17/20 = around 0.85</output>

<gadget id="calculator">1 - (17/20)</gadget>
<output>3/20 = around 0.15</output>

<gadget id="calculator">100 * (3/20)</gadget>
<output>15</output>

<gadget id="calculator">93 / 100</gadget>
<output>93/100 = around 0.93</output>

<gadget id="calculator">1 - (93/100)</gadget>
<output>7/100 = around 0.07</output>

<gadget id="calculator">100 * (7/100)</gadget>
<output>7</output>

<gadget id="calculator">20 + 15 + 7</gadget>
<output>42</output>

<gadget id="calculator">76 - 42</gadget>
<output>34</output>

<gadget id="calculator">34 / 100</gadget>
<output>17/50 = around 0.34</output>

<result>17/50 = around 0.34</result>
