Помогите, пожалуйста

Answer 1

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