Answer 1

$\frac{6}{8} \times \frac{1}{3} = \frac{2}{8} = \frac{1}{4} \\ \\ \frac{5}{3} \times \frac{4}{6} = \frac{5}{3} \times \frac{2}{3} = \frac{10}{9} \\ \\ \frac{9}{3} \times \frac{1}{7} = 3 \times \frac{1}{7} = \frac{3}{7} \\ \\ \frac{8}{5} \times \frac{3}{2} = \frac{4}{5} \times 3 = \frac{12}{5} \\ \\ \\ \frac{4}{5} \times \frac{3}{7} = \frac{4 \times 3}{5 \times 7} = \frac{12}{35} \\ \\ \frac{2}{3} \div \frac{5}{4} = \frac{2}{3} \times \frac{4}{5} = \frac{8}{15}$
