Ответ:
[tex] \frac{( \frac{5}{6} + \frac{1}{2}) \div \frac{7}{12 } }{ - \frac{5}{9} + (11 - 7 \frac{5}{18} ) } = [/tex]
1 действие решим в скобках
[tex] \frac{5}{6} + \frac{1}{2} = \frac{5}{6} + \frac{3}{3 \times 2} = \frac{8}{6} [/tex]
[tex]11 - 7 \frac{5}{18} = 10 \frac{18}{18} - 7 \frac{5}{18} = 3 \frac{13}{18} [/tex]
[tex] = \frac{ \frac{8}{6} \div \frac{7}{12} }{ - \frac{5}{9} + 3 \frac{13}{18} } = [/tex]
2 рассчитаем числитель
[tex] \frac{8}{6} \div \frac{7}{12} = \frac{8}{6} \frac{12}{7} = \frac{8 \times 2}{7} = \frac{16}{7} [/tex]
3 рассчитаем знаменатель
[tex] - \frac{5}{9} + 3 \frac{13}{18} = 3 \frac{13}{18} - \frac{10}{18} = 3 \frac{3}{18} = \frac{57}{18} [/tex]
[tex] = \frac{ \frac{16}{7} }{ \frac{57}{18} } = \frac{16}{7} \frac{18}{57} = \frac{288}{399} [/tex]
