tính [92-1/9-2/10-3/11-...-92/100]:[1/45+/50+1/55+...+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 +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
Tính E/F
a) So sánh: -22/45 và -51/103
b) Tính:
( 92 - 1/9 - 2/10 - 3/11 - ... - 92/100 ) : ( 1/45 + 1/50 + 1/55 + ... + 1/500 )
cho M=92-1/9-2/10-3/11-...-92/100
N=1/45=1/50+1/55+...+1/500
tính M.N
Tính:\(B=\frac{92-\frac{1}{9}-\frac{2}{10}-\frac{3}{11}-.....-\frac{92}{100}}{\frac{1}{45}+\frac{1}{50}+\frac{1}{55}+....+\frac{1}{500}}\)
Tính N=\(\frac{92-\frac{1}{9}-\frac{2}{10}-\frac{3}{11}-...-\frac{92}{100}}{\frac{1}{45}+\frac{1}{50}+\frac{1}{55}+...+\frac{1}{500}}\)
Tính :
\(A=\frac{92-\frac{1}{9}-\frac{2}{10}-\frac{3}{11}-...-\frac{92}{100}}{\frac{1}{45}+\frac{1}{50}+\frac{1}{55}+...+\frac{1}{500}}\)
