Помогите, пожалуйста

Answer 1

$11 \times ( \frac{4}{9} + \frac{2}{3} ) - 1 \div \frac{7}{5} \times \frac{14}{45} = 12 \\ 1) \frac{4}{9} + \frac{2}{3} = \frac{4 + 6}{9} = \frac{10}{9} \\ 2)11 \times \frac{10}{9} = \frac{11 \times 10}{9} = \frac{110}{9} \\ 3)1 \div \frac{7}{5} = \frac{1 \times 5}{7} = \frac{5}{7} \\ 4) \frac{5}{7} \times \frac{14}{45} = \frac{5 \times 14}{7 \times 45} = \frac{1 \times 2}{1 \times 9} = \frac{2}{9} \\ 5) \frac{110}{9} - \frac{2}{9} = \frac{108}{9} = 12$
