[tex]a) \frac{3}{5} \times \frac{2}{3} = \frac{2}{5} [/tex]

[tex]b) \frac{3}{5} \times \frac{9}{6} = \frac{1}{5} \times \frac{9}{2} = \frac{1 \times 9}{5 \times 2} = \frac{9}{10} [/tex]

[tex]c) \frac{4}{6} \times \frac{6}{8} = \frac{4}{8} = \frac{1}{2} [/tex]

[tex]d) \frac{11}{12} \times \frac{24}{33} = 1 \times \frac{2}{3} = \frac{1 \times 2}{3} = \frac{2}{3} [/tex]
