Ответ:
- При \(x=\frac{3}{4}\): \(\frac{14}{15}\cdot\frac{3}{4}=\frac{7}{10}\).
- При \(x=\frac{5}{7}\): \(\frac{14}{15}\cdot\frac{5}{7}=\frac{2}{3}\).
- При \(x=\frac{15}{28}\): \(\frac{14}{15}\cdot\frac{15}{28}=\frac{1}{2}\).
- При \(x=\frac{10}{21}\): \(\frac{14}{15}\cdot\frac{10}{21}=\frac{4}{9}\).
Ответ: \(\frac{7}{10};\frac{2}{3};\frac{1}{2};\frac{4}{9}\).
