Bài 326:
\(=\left(1+\dfrac{1}{2}\right)+\left(1+\dfrac{1}{6}\right)+...+\left(1+\dfrac{1}{90}\right)\\ =\left(1+1+...+1\right)+\left(\dfrac{1}{1.2}+\dfrac{1}{2.3}+\dfrac{1}{3.4}+...+\dfrac{1}{9.10}\right)\\ =9+\left(1-\dfrac{1}{2}+\dfrac{1}{2}-\dfrac{1}{3}+...+\dfrac{1}{9}-\dfrac{1}{10}\right)\\ =9+\left(1-\dfrac{1}{10}\right)=9+\dfrac{9}{10}=\dfrac{99}{10}\)
Sau lần xuất quân thứ nhất số phần trăm vận động viên còn lại:
\(100\%-60\%=40\%\)
Sau lần xuất quân thứ hai số phần trăm chỉ vận động viên còn lại:
\(40\%\times50\%=20\%\)
Tổng số vận động viên là:
\(141:20\%=705\) (vận động viên)
Tổng số vận động viên xuất quân trong 2 đợt đầu tiên:
\(705-141=564\) (vận động viên)
Đáp số: 564 vận động viên
