Помогите решить срочно!!!! ​

Answer 1

Ответ:

$1 \frac{1}{3}$

Пошаговое объяснение:

$(14 - 2 \frac{11}{12} \div \frac{7}{18} ) \div 4 \frac{7}{8} = \\ = (14 - \frac{35}{12} \times \frac{18}{7} ) \div \frac{39}{8} = \\ = (14 - \frac{5 \times 3}{2 \times 1} ) \div \frac{39}{8} = \\ = (14 - \frac{15}{2} ) \div \frac{39}{8} = \\ = \frac{14 \times 2 - 15}{2} \times \frac{8}{39} = \\ = \frac{13}{2} \times \frac{8}{39} = \frac{1 \times 4}{1 \times 3} = \frac{4}{3} = 1 \frac{1}{3}$
