Решение:

1. \( \frac{2}{13} \cdot 5 = \frac{2 \cdot 5}{13} = \frac{10}{13} \)
2. \( \frac{4}{17} \cdot 3 = \frac{4 \cdot 3}{17} = \frac{12}{17} \)
3. \( \frac{8}{9} \cdot 2 = \frac{8 \cdot 2}{9} = \frac{16}{9} = 1 \frac{7}{9} \)
4. \( \frac{4}{49} \cdot 7 = \frac{4 \cdot 7}{49} = \frac{4 \cdot 1}{7} = \frac{4}{7} \)
5. \( 7 \cdot \frac{3}{40} = \frac{7 \cdot 3}{40} = \frac{21}{40} \)
6. \( \frac{15}{18} \cdot 6 = \frac{15 \cdot 6}{18} = \frac{15 \cdot 1}{3} = 5 \)
7. \( \frac{7}{12} \cdot 24 = \frac{7 \cdot 24}{12} = 7 \cdot 2 = 14 \)
8. \( 45 \cdot \frac{8}{15} = \frac{45 \cdot 8}{15} = 3 \cdot 8 = 24 \)

Ответ: 1) \( \frac{10}{13} \); 2) \( \frac{12}{17} \); 3) \( 1 \frac{7}{9} \); 4) \( \frac{4}{7} \); 5) \( \frac{21}{40} \); 6) \( 5 \); 7) \( 14 \); 8) \( 24 \).
