14 целых 1/6-(8целых 9/10-5целых 2/3)

Решите задачу:

$14 \frac{1}{6} - (8 \frac{9}{10} - 5 \frac{2}{3} ) = \frac{85}{6} - ($

$\frac{89}{10} - \frac{17}{3} ) = \frac{85}{6} - \frac{89 \times 3 - 17 \times 10}{30} =$

$\frac{85}{6} - \frac{267 - 170}{30} = \frac{85}{6} - \frac{97}{30} =$

$\frac{85 \times 5 - 97 \times 1}{30} = \frac{328}{30} = \frac{164}{15} = 10 \frac{14}{15}$
