d=1/2+5/6+11/12+...+9899/9900
1/2+5/6+11/12+...+9899/9900
tính hộ mình nhé! mình cần đáp án nhanh.
Cho tổng A=1/2+5/6+11/12+19/20+...+9701/9702+9899/9900
Chứng tỏ A<99
Tính nhanh
\(\frac{1}{2}+\frac{5}{6}+\frac{11}{12}+.....+\frac{9899}{9900}\)
\(\frac{1}{2}\)+\(\frac{5}{6}\)+\(\frac{11}{12}\)+...+\(\frac{9899}{9900}\)
thực hiện phép tính
A=\(100.\left(1+\frac{5}{6}+\frac{11}{12}+\frac{19}{20}+...+\frac{9899}{9900}\right)\)
tính tổng
\(100\cdot\)(\(1+\frac{5}{6}+\frac{11}{12}+\frac{19}{20}+.......+\frac{9899}{9900}\))
a/ 1/2 + 5/6 + 11/12 + 19/20
b/ 1/2 + 5/6 + 11/12 + 19/20 + 29/30 + 41/42
c/ (1-1/3) + (1-1/15) + (1-1/35) + (1-1/63)
d/ 1/2 + 5/6 + 11/12 + ... + 9899/9900
e/ 2/3 + 14/15 + 34/35 +62/63
f/ 2/3 + 14/15 + 34/35 + ... + 9998/9999
1/2+5/6+...+9899/9900 = ?
