There are about 200 students who participated in the mathematics competition in the fifth grade of a certain school. Those who scored 90-100 points accounted for (1/7) of the total number of participants, and those who scored 80-89 points accounted for (1/7) of the total number of participants. 5), those who scored 70-79 points accounted for exactly (1/3) of the total number of participants, so how many people scored below 70 points?
某校五年级参加数学竞赛的同学约有二百多人，考试成绩是得90-100的恰好占参赛总人数的(1/7)，得80-89分的占参赛总人数的(1/5)，得70-79分的恰好占参赛总人数的(1/3)，那么70分以下的有多少人．

<output>1/7 = around 0.142857</output>

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

<gadget id="calculator">1 / 3</gadget>
<output>1/3 = around 0.333333</output>

<gadget id="calculator">1 - (1/7) - (1/5) - (1/3)</gadget>
<output>34/105 = around 0.32381</output>
