Помогите все решить, срочно нужно

= \frac{6}{5} \times (\frac{9}{12} - \frac{4}{12}) = \frac{6}{5} \times \frac{5}{12} = \frac{1}{1} \times \frac{1}{2} = \frac{1}{2}

" alt="1 \frac{1}{5} \times (\frac{3}{4} - \frac{1}{3})

= \frac{6}{5} \times (\frac{9}{12} - \frac{4}{12}) = \frac{6}{5} \times \frac{5}{12} = \frac{1}{1} \times \frac{1}{2} = \frac{1}{2}

$(1 \frac{1}{3} - \frac{5}{6} ) \times 18 = ( \frac{4}{3} - \frac{5}{6} ) \times 18 = ( \frac{8}{6} - \frac{5}{6} ) \times 18 = \frac{3}{6} \times 18 =\frac{1}{2} \times 18 =\frac{1}{2} \times \frac{18}{1} = \frac{18}{2} = 9$

Удачи)))
