Answer 1

Ответ:

$\frac{0.25 \times 0.17 \times 0.7}{0.34 \times 0.75 \times 0.49} = \frac{ \frac{25}{100} \times \frac{17}{100} \times \frac{7}{10} }{ \frac{34}{100} \times \frac{75}{100} \times \frac{49}{100} } = \frac{25}{100} \times \frac{17}{100} \times \frac{7}{10} \div( \frac{34}{100} \times \frac{75}{100} \times \frac{49}{100} ) = \frac{25}{100} \times \frac{17}{100} \times \frac{7}{10} \times \frac{100}{34} \times \frac{100}{75} \times \frac{100}{49} = \frac{ 10}{2 \times3 \times 7 } = \frac{10}{42} = \frac{5}{21}$
