Ответ:
[tex]2\frac{2}{165}[/tex]
Пошаговое объяснение:
[tex]\frac{2}{3}+\frac{4}{5}+\frac{6}{11}=\frac{2\cdot 5}{3\cdot 5}+\frac{4\cdot 3}{5\cdot 3}+\frac{6}{11}=\frac{10}{15}+\frac{12}{15}+\frac{6}{11}=\frac{22}{15}+\frac{6}{11}=\\\\\frac{22\cdot 11}{15\cdot 11}+\frac{6\cdot 15}{11\cdot 15}=\frac{242}{165}+\frac{90}{165}=\frac{332}{165}=2\frac{2}{165}[/tex]
