  1. $\text{Giải đáp + Lời giải và giải thích chi tiết:}$
    $\text{A = (6 – $\dfrac{2}{3}$ + $\dfrac{1}{2}$) – (5 – $\dfrac{5}{3}$ + $\dfrac{3}{2}$) – (3 – $\dfrac{7}{3}$ + $\dfrac{5}{2}$)}$
    $\text{Vì bài dài quá nên mình tách thành từng phần nhé}$
    $\text{$\dfrac{36}{6}$ – $\dfrac{4}{6}$ + $\dfrac{3}{6}$ = $\dfrac{35}{6}$}$
    $\text{$\dfrac{30}{6}$ – $\dfrac{10}{6}$ + $\dfrac{9}{6}$ = $\dfrac{29}{6}$}$
    $\text{$\dfrac{18}{6}$ – $\dfrac{14}{6}$ + $\dfrac{15}{6}$ = $\dfrac{19}{6}$}$
    $\text{Vậy A = $\dfrac{35}{6}$ – $\dfrac{29}{6}$ – $\dfrac{19}{6}$ = $\dfrac{-13}{6}$}$
     

  2. A= (6 – 2/3 +1/2) – (5 – 5/3 + 3/2) – (3 – 7/3 + 5/2)
    =(36/6-4/6+3/6)-(30/6-10/6+9/6)-(18/3-14/6+15/6)
    =(36-4+3)/6-(30-10+9)/6-(18-14+15)/6
    =35/6-29/6-19/6
    =-13/6
