计算: $\frac{1}{5}+\frac{1}{5}+\frac{3}{5}$= | $\frac{2}{11}+\frac{6}{11}+\frac{1}{11}$= | $\frac{7}{33}+\frac{10}{33}+\frac{5}{33}$= |
$\frac{8}{9}-\frac{2}{9}-\frac{4}{9}$= | $1-\frac{2}{15}-\frac{13}{15}$= | $\frac{17}{51}-\frac{8}{51}-\frac{4}{51}$= |
$\frac{19}{20}-\frac{13}{20}-\frac{3}{20}$= | $\frac{11}{22}+\frac{3}{22}+\frac{5}{22}$= | $\frac{2}{3}+\frac{5}{3}+\frac{8}{3}$= |
