At the party, 3 students hosted the program, and the rest of the students (5/11) performed the program, so half of the students in the class were left as the audience. How many people are there in the class?
联欢会上，3名同学主持节目，余下同学中的(5/11)表演节目，这样正好还剩全班同学的一半做观众，全班一共有多少人？

<output>15/11 = around 1.363636</output>

<gadget id="calculator">3 - (15/11)</gadget>
<output>18/11 = around 1.636364</output>

<gadget id="calculator">1 / 2</gadget>
<output>1/2 = around 0.5</output>

<gadget id="calculator">(1/2) - (5/11)</gadget>
<output>1/22 = around 0.045455</output>

<gadget id="calculator">(18/11) / (1/22)</gadget>
