8. Расположите дроби в порядке убывания: \(\frac{3}{15}\), \(\frac{7}{5}\), \(\frac{9}{15}\), \(\frac{11}{15}\), \(\frac{15}{15}\), \(\frac{15}{15}\), \(\frac{11}{15}\), \(\frac{9}{15}\), \(\frac{7}{5}\), \(\frac{3}{15}\) A) C) \(\frac{3}{15}\) \(\frac{9}{15}\) \(\frac{11}{15}\) \(\frac{15}{15}\) \(\frac{7}{5}\) \(\frac{7}{5}\) \(\frac{15}{15}\) \(\frac{11}{15}\) \(\frac{9}{15}\) \(\frac{3}{15}\) B) D)

Сравним дроби, приведя их к общему знаменателю 15:

• \(\frac{3}{15}\)
• \(\frac{7}{5} = \frac{7 \cdot 3}{5 \cdot 3} = \frac{21}{15}\)
• \(\frac{9}{15}\)
• \(\frac{11}{15}\)
• \(\frac{15}{15} = 1\)

Расположим в порядке убывания: \(\frac{7}{5}\), \(\frac{15}{15}\), \(\frac{11}{15}\), \(\frac{9}{15}\), \(\frac{3}{15}\)

Ответ: D) \(\frac{7}{5}\), \(\frac{7}{5}\), \(\frac{15}{15}\), \(\frac{11}{15}\), \(\frac{9}{15}\), \(\frac{3}{15}\)
