Respuesta:

$\frac{6}{8} \times \frac{3}{5} = \frac{18}{40} = \frac{9}{20} \\2 \frac{8}{9} \times \frac{1}{2} = \frac{26}{9} \times \frac{1}{2} = \frac{26}{18} = \frac{13}{9} = 1 \frac{4}{9} \\ \frac{3}{10} \times 4 \frac{5}{6} = \frac{3}{10} \times \frac{29}{6} = \frac{87}{60} = \frac{29}{20} = 1 \frac{9}{20} \\ 8 \frac{1}{8} \times \frac{1}{3} = \frac{65}{8} \times \frac{1}{3} = \frac{65}{24} = 2\frac{17}{24} \\ 5 \frac{2}{3} \times \frac{1}{5} = \frac{17}{3} \times \frac{1}{5} = \frac{17}{15} = 1 \frac{2}{15}$

$8 \frac{1}{2} \times \frac{2}{5} = \frac{17}{2} \times \frac{2}{5} = \frac{34}{10} = \frac{17}{5} = 3 \frac{2}{5} \\ 3 \frac{2}{3} \times \frac{1}{7} = \frac{11}{3} \times \frac{1}{7} = \frac{11}{21} \\ \frac{3}{10} \div \frac{5}{6} = \frac{3 \times 6}{10 \times 5} = \frac{18}{50} = \frac{9}{25} \\ \frac{7}{8} \div \frac{3}{4} = \frac{7 \times 4}{8 \times 3} = \frac{28}{24} = \frac{14}{12} = \frac{7}{6} = 1 \frac{1}{6}$
