Пошаговое объяснение:
[tex] - 3 \frac{3}{5} + ( - 2 \frac{1}{3} ) + 4 \frac{8}{15} - 1 \frac{5}{6} - ( - 6 \frac{7}{10} ) + \frac{1}{2} = - 5 \frac{14}{15} + 4 \frac{8}{15} - 1 \frac{5}{6} - ( - 6 \frac{7}{10} ) + \frac{1}{2} = - 1 \frac{2}{5} - 1 \frac{5}{6} - ( - 6 \frac{7}{10} ) + \frac{1}{2} = - 3 \frac{7}{30} - ( - 6 \frac{7}{10} ) + \frac{1}{2} = 3 \frac{7}{15} + \frac{1}{2} = 3 \frac{29}{30} [/tex]
