Срочно помогите осталось 6 примеров пж решите. 1) 8целых 6/35-6целых 7/10 2)15целых...

Решите задачу:

$1)8 \frac{6}{35} - 6 \frac{7}{10} = \frac{286}{35} - \frac{67}{10} = \frac{2860 - 2345}{350} = \frac{515}{350} \\ 2)15 \frac{8}{21} - 6 \frac{5}{14} = \frac{323}{21} - \frac{89}{14} = \frac{4522 - 1869}{294} = \frac{2653}{294} \\ 3)7 \frac{3}{8} + 9\frac{7}{16} + 11 \frac{7}6 \frac{}{} {12} = \frac{59}{8} + \frac{151}{16} + \frac{139}{12} = \frac{354 + 453 + 556}{48} = \frac{1363}{48} \\ 4)6 \frac{19}{48} - 5 \frac{11}{32} = \frac{307}{48} - \frac{171}{32} = \frac{614 - 513}{96} = \frac{101}{96} \\ 5)7 \frac{5}{16} + 4 \frac{1}{6} + 3 \frac{3}{8} = \frac{117}{16} + \frac{25}{6} + \frac{27}{8} = \frac{351 + 200 + 162}{48} = \frac{713}{48} \\$
