    Giải thích các bước giải:

    $\ A = \dfrac{0,5 – \dfrac{3}{17} + \dfrac{3}{17}}{\dfrac{5}{6} – \dfrac{5}{17} + \dfrac{5}{37}} + \dfrac{0,5 – \dfrac{1}{3} + \dfrac{1}{4} – 0,2}{\dfrac{7}{5} – \dfrac{7}{4} + \dfrac{7}{3} – 3,5}$

    $\ A = \dfrac{\dfrac{1}{2} – \dfrac{3}{17} + \dfrac{3}{17}}{\dfrac{5}{6} – \dfrac{5}{17} + \dfrac{5}{37}} + \dfrac{\dfrac{1}{2} – \dfrac{1}{3} + \dfrac{1}{4} – \dfrac{1}{5}}{\dfrac{7}{5} – \dfrac{7}{4} + \dfrac{7}{3} – \dfrac{7}{2}}$

    $\ A = \dfrac{\dfrac{1}{2} }{\dfrac{2545}{3774}} + {\dfrac{\dfrac{13}{60}}{\dfrac{-91}{60}}}$

    $A=\dfrac{\dfrac{1}{2}}{\dfrac{2545}{3774}}+\dfrac{13}{-91}$

    `A=1/2:2545/3774+13/-91`

    `A=3774/5090+13/-91`

    `A=10664 /17815`
