[tex]a) \frac{5}{8} \times \frac{1}{10} = \frac{1}{16} \\ \frac{3}{4} \times \frac{1}{3} = \frac{1}{4} \\ 1 \frac{1}{3} \times \frac{1}{6} = \frac{4}{3} \times \frac{1}{6} = \frac{2}{9} \\ 2 \frac{1}{5} \times \frac{1}{22} = \frac{11}{5} \times \frac{1}{22} = \frac{1}{10} \\ [/tex]
[tex]b)2 \times \frac{5}{2} = 5 \\ 6 \times \frac{10}{9} = \frac{20}{3} = 6 \frac{2}{3} \\ 3 \times \frac{2}{3} = 2 \\ 10 \times \frac{3}{10} = 3[/tex]
[tex]c) \frac{1}{2} \times \frac{4}{3} = \frac{2}{3} \\ \frac{4}{5} \times \frac{7}{6} = \frac{14}{15} \\ \frac{5}{8} \times \frac{10}{3} = \frac{25}{12} = 2 \frac{1}{2} \\ \frac{4}{9} \times \frac{6}{5} = \frac{8}{15} [/tex]
[tex]d) \frac{5}{7} \times \frac{5}{7} = \frac{25}{49} \\ \frac{12}{5} \times \frac{9}{4} = \frac{27}{5} = 5 \frac{2}{5} \\ \frac{3}{4} \times \frac{8}{9} = \frac{2}{3} \\ \frac{14}{3} \times \frac{8}{7} = \frac{16}{3} = 5 \frac{1}{3} [/tex]
