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) \(\frac{4}{49} \cdot 7 = \frac{4 \cdot 7}{49} = \frac{4}{7}\) 5) \(7 \cdot \frac{3}{40} = \frac{7 \cdot 3}{40} = \frac{21}{40}\) 6) \(6 \cdot \frac{15}{18} = \frac{6 \cdot 15}{18} = \frac{90}{18} = 5\) 7) \(\frac{7}{12} \cdot 24 = \frac{7 \cdot 24}{12} = \frac{7 \cdot 2}{1} = 14\) 8) \(45 \cdot \frac{8}{15} = \frac{45 \cdot 8}{15} = 3 \cdot 8 = 24\)
