Ответ:
1[tex]\frac{2}{3}[/tex]
Пошаговое объяснение:
(1 2/3 * 2 1/5 + 1) / (2 1/5) - 5/11 = (3[tex]\frac{2}{3}[/tex] + 1) / 2[tex]\frac{1}{5}[/tex] - [tex]\frac{5}{11}[/tex] = 4 [tex]\frac{2}{3}[/tex] / 2 [tex]\frac{1}{5}[/tex] = 2 [tex]\frac{4}{33}[/tex] - [tex]\frac{5}{11}[/tex] = [tex]\frac{5}{3}[/tex] = [tex]1\frac{2}{3}[/tex]
