Решение:

• \( \frac{5}{7} = \frac{5 \cdot 5}{7 \cdot 5} = \frac{25}{35} \)
• \( \frac{7}{12} = \frac{7 \cdot 5}{12 \cdot 5} = \frac{35}{60} \)
• \( \frac{8}{11} = \frac{8 \cdot 7}{11 \cdot 7} = \frac{56}{77} \)
• \( 15 = \frac{15 \cdot 1}{1} = \frac{15 \cdot 3}{1 \cdot 3} = \frac{45}{3} \)
• \( 3 \frac{1}{24} = \frac{3 \cdot 24 + 1}{24} = \frac{72+1}{24} = \frac{73}{24} \)
• \( 5 \frac{1}{72} = \frac{5 \cdot 72 + 1}{72} = \frac{360+1}{72} = \frac{361}{72} \)

Ответ: \( \frac{25}{35} \); \( \frac{35}{60} \); \( \frac{56}{77} \); \( \frac{45}{3} \); \( \frac{73}{24} \); \( \frac{361}{72} \).
