Ученикам 6 класса ВПРОС

Answer 1

$- \frac{2}{5} - \frac{1}{10} = - ( \frac{4}{10} + \frac{1}{10)} = - \frac{5}{10} = - \frac{1}{2} = - .0.5$

Answer 2

$- \frac{1}{3} \times \frac{6}{5} - \frac{5}{6} \times \frac{3}{25} = - \frac{2}{5} - \frac{1}{2} \times \frac{1}{25} = - \frac{2}{5} - \frac{1}{10} = - \frac{1}{2} = - 0.5$

Удачи))))
