\(\frac{10-\frac{1}{9}-\frac{2}{10}-\frac{3}{11}-\frac{4}{12}-...-\frac{10}{18}}{\frac{1}{45}+\frac{1}{50}+\frac{1}{55}+\frac{1}{60}+...+\frac{1}{90}}\)
tính B = (80 - 1/9 - 2/10-3/11- 4/12-...-80/88):(1/45+1/50+1/55+...+1/440)
Tính \(H=\left[101-\frac{1}{9}-\frac{2}{10}-\frac{3}{11}-...-\frac{101}{109}\right]:\left[\frac{1}{45}+\frac{1}{50}+\frac{1}{55}+...+\frac{1}{545}\right]\)
Tính A=92-1/9-2/10-3/11-4/12-5/3-...-91/99-92/100 / 1/45+1/50+1/55+...+1/495+1/500
(92-1/9-2/10-3/11-...-92/100)/(1/45+1/50+1/55+...+1/500)
tính [92-1/9-2/10-3/11-...-92/100]:[1/45+/50+1/55+...+1/500]
Cho M =1/99+2/98+3/97+.........+99/1/1/2+1/3+1/4+.........+1/100 va N = 92-1/9-2/10-3/11-......-92/100/1/45+1/50+1/55+......+1/500. Tinhs M-2.N = ?
tính :
(92 -1/9 -2/10 -3/11 -..... -92/100 ) :(1/45 +1/50 +1/55 +..... +1/500)
Cho E=92-1\9-2\10-3\11-...-92\100; F=1\45+1\50+1\55+...+1\500
