When a certain class gathers once, the number of people who ask for leave is 1/9 of the number of people present, and one person asks for leave and leaves in the middle. In this way, the number of people who ask for leave is 3/22 of the number of people present, so how many people are there in this class?
某班一次集合，请假人数是出席的人数的(1/9)，中途又有一人请假离开，这样一来请假人数是出席人数的(3/22)，那么这个班共有多少人？

<gadget id="calculator">3 / 25</gadget>
<output>3/25 = around 0.12</output>

<gadget id="calculator">1 + 9</gadget>
<output>10</output>

<gadget id="calculator">1 / 10</gadget>
<output>1/10 = around 0.1</output>

<gadget id="calculator">(3/25) - (1/10)</gadget>
<output>1/50 = around 0.02</output>

<gadget id="calculator">1 / (1/50)</gadget>
<output>50</output>
