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