  1. Giải đáp:
     Lời giải và giải thích chi tiết:
    a) $\frac{6}{7}×$ $\frac{5}{3}:$ $\frac{2}{7}=$ $\frac{10}{7} ×$ $\frac{7}{2}=5$
    b) $\frac{60}{7}:$ $\frac{12}{11}× 2=$ $\frac{60}{7}×$ $\frac{11}{12}× 2=$ $\frac{132}{7}× 2 =$ $\frac{264}{7}$ 
    c) $4:\frac{5}{8}×$ $\frac{3}{16}= $ $\frac{32}{5}× $ $\frac{3}{16}=$ $\frac{6}{5}$ 
    d) $\frac{15}{13}:$ $\frac{25}{26}:3=$ $\frac{15}{13}×$ $\frac{26}{25}:3=$ $\frac{6}{5}×$ $\frac{1}{3}=$ $\frac{2}{5}$ 
    xin hn ạ

  2. $\textit{Giải đáp + Lời giải và giải thích chi tiết:}$
    $\text{$\dfrac{6}{7}$ x $\dfrac{5}{3}$ : $\dfrac{2}{7}$}$
    $\text{= $\dfrac{6}{7}$ x $\dfrac{5}{3}$ x $\dfrac{7}{2}$}$
    $\text{= 5}$
    $\text{$\dfrac{60}{7}$ : $\dfrac{12}{11}$ x 2}$
    $\text{= $\dfrac{60}{7}$ x $\dfrac{11}{12}$ x 2}$
    $\text{= $\dfrac{110}{7}$}$
    $\text{4 : $\dfrac{5}{8}$ x $\dfrac{3}{16}$}$
    $\text{= 4 x $\dfrac{8}{5}$ x $\dfrac{3}{16}$}$
    $\text{$\dfrac{6}{5}$}$
    $\text{$\dfrac{15}{13}$ : $\dfrac{25}{26}$ : 3}$
    $\text{= $\dfrac{15}{13}$ x $\dfrac{26}{25}$ x $\dfrac{1}{3}$}$
    $\text{= $\dfrac{2}{5}$}$
