Đáp án:

 $\dfrac{7}{3}$

Giải thích các bước giải:

 $1+\dfrac{4-\dfrac{4}{29}+\dfrac{4}{41}+\dfrac{4}{2015}}{3-\dfrac{3}{29}+\dfrac{3}{41}+\dfrac{4}{2015}}\\
=1+\dfrac{4}{3}\dfrac{3.\left (4-\dfrac{4}{29}+\dfrac{4}{41}+\dfrac{4}{2015}  \right )}{4.\left (3-\dfrac{3}{29}+\dfrac{3}{41}+\dfrac{4}{2015}  \right )}\\
=1+\dfrac{4}{3}\dfrac{12-\dfrac{12}{29}+\dfrac{12}{41}+\dfrac{12}{2015}}{12-\dfrac{12}{29}+\dfrac{12}{41}+\dfrac{12}{2015}}\\
=1+\dfrac{4}{3}\\
=\dfrac{3}{3}+\dfrac{4}{3}\\
=\dfrac{7}{3}$
