There are a total of 100 students participating in the mathematics interest group. If the boys are called out (1/5) and the girls are called out to 10 people, then the number of boys and girls is equal. How many boys and girls are there?
参加数学兴趣小组的同学共有100人，如果男生调出(1/5)，女生调出10人，这时男女生人数相等．男女生原来个有多少人？
<gadget id="calculator">100 - 10</gadget>
<output>90</output>

<gadget id="calculator">1 / 5</gadget>
<output>1/5 = around 0.2</output>

<gadget id="calculator">1 - (1/5)</gadget>
<output>4/5 = around 0.8</output>

<gadget id="calculator">1 + (4/5)</gadget>
<output>9/5 = around 1.8</output>

<gadget id="calculator">90 / (9/5)</gadget>
<output>50</output>

<gadget id="calculator">100 - 50</gadget>
<output>50</output>

<result>50</result>
