Lời giải:
\(\frac{1719}{3976}=\frac{1}{2+\frac{538}{1719}}=\frac{1}{2+\frac{1}{3+\frac{105}{538}}}=\frac{1}{2+\frac{1}{3+\frac{1}{5+\frac{13}{105}}}}=\frac{1}{2+\frac{1}{3+\frac{1}{5+\frac{1}{8+\frac{1}{13}}}}}\)
$\Rightarrow a=8; b=13$

\(\dfrac{1719}{3976}=\dfrac{1}{\dfrac{3976}{1719}}=\dfrac{1}{2+\dfrac{538}{1719}}=\dfrac{1}{2+\dfrac{1}{\dfrac{1719}{538}}}=\dfrac{1}{2+\dfrac{1}{3+\dfrac{105}{538}}}\)
\(=\dfrac{1}{2+\dfrac{1}{3+\dfrac{1}{\dfrac{538}{105}}}}=\dfrac{1}{2+\dfrac{1}{3+\dfrac{1}{5+\dfrac{13}{105}}}}=\dfrac{1}{2+\dfrac{1}{3+\dfrac{1}{5+\dfrac{1}{\dfrac{105}{13}}}}}\)
\(=\dfrac{1}{2+\dfrac{1}{3+\dfrac{1}{5+\dfrac{1}{8+\dfrac{1}{13}}}}}\)

\(A=\frac{17}{18}+\frac{1717}{1818}+\frac{171717}{181818}+...+\frac{1717..17}{1818...18}\)(2018 số 17 và 18)
\(=\frac{17}{18}+\frac{17.101}{18.101}+\frac{17.10101}{18.10101}+...+\frac{17.1010...01}{18.1010...01}\)(2017 cặp số 10 liên tiếp và dư 1 số 1)
\(=\frac{17}{18}+\frac{17}{18}+\frac{17}{18}+...+\frac{17}{18}\left(2018\text{ số hạng}\right)\)
\(=\frac{17}{18}.2018=\frac{17153}{9}\)
