  1. 8$\frac{3}{7}$ – (2$\frac{2}{3}$ + 5$\frac{3}{7}$)
    = $\frac{59}{7}$- ($\frac{8}{3}$ + $\frac{38}{7}$)
    = $\frac{59}{7}$- $\frac{170}{21}$
    = $\frac{1}{3}$
    Xin hay nhất ạ 

  2. 8{3}/7-(2{2}/3+5{3}/7)
    =8{3}/7-2{2}/3-5{3}/7
    =59/7-8/3-38/7
    =(59/7-38/7)-8/3
    =21/7-8/3
    =3-8/3
    =9/3-8/3
    =1/3
