Tính tổng: A =\(\frac{38}{25}\)+ \(\frac{9}{10}\)- \(\frac{11}{15}\)+ \(\frac{13}{21}\) - \(\frac{15}{28}\) + \(\frac{17}{36}\)- ..... + \(\frac{197}{4851}\)- \(\frac{199}{4950}\)

Answer 1

[Nguyễn Ngọc Anh Minh]

Sorry

\(\frac{B}{2}=\frac{1}{4}-\frac{1}{100}=\frac{24}{100}\) => \(B=\frac{12}{25}\)

\(A=\frac{38}{25}+\frac{12}{25}=2\)
