    1/3 – 2/9
    = 3/9 – 2/9
    = 1/9
    1 + 2/3
    = 3/3 + 2/3
    = 5/3
    1/3 + 5/9
    = 3/9 + 5/9
    = 8/9
    1 – 8/9
    = 9/9 – 8/9
    = 1/9
    3/2 + 2/3
    = 9/6 + 4/6
    = 13/6
    1/2 + 7/6
    = 3/6 + 7/6
    = 10/6
    = 5/3
    1 – 1/9
    = 9/9 – 1/9
    = 7/9

    Lời giải chi tiết :
    $\frac{1}{3}$ – $\frac{2}{9}$
    = $\frac{3}{9}$ + $\frac{-2}{9}$
    = $\frac{1}{9}$
    1+$\frac{2}{3}$
    = $\frac{3}{3}$ + $\frac{2}{3}$
    =$\frac{5}{3}$ 
    $\frac{1}{3}$ + $\frac{5}{9}$
    =$\frac{3}{9}$ + $\frac{5}{9}$
    = $\frac{8}{9}$
    1 – $\frac{8}{9}$\
    = $\frac{9}{9}$ + $\frac{-8}{9}$
    = $\frac{1}{9}$
    $\frac{3}{2}$ + $\frac{2}{3}$
    = $\frac{9}{6}$ + $\frac{4}{6}$
    = $\frac{13}{6}$
    $\frac{1}{2}$ + $\frac{7}{6}$
    = $\frac{3}{6}$ + $\frac{7}{6}$
    = $\frac{10}{6}$
    = $\frac{5}{3}$
    1-$\frac{1}{9}$ = $\frac{9}{9}$ + $\frac{-1}{9}$ =$\frac{8}{9}$
