Solution:
[tex]1. \frac{13}{15} \times \frac{2}{3} \\ = \frac{26}{45} \\ 2. \frac{4}{5} \times \frac{8}{16} \\ = \frac{4}{5} \times \frac{1}{2} \\ = \frac{2}{5} [/tex]
[tex]3. \frac{4}{24} \times \frac{2}{6} \\ = \frac{1}{6} \times \frac{1}{3} \\ = \frac{1}{18} [/tex]
[tex]4. \frac{1}{2} \times \frac{1}{5} = \frac{1}{10} \\ 5.1 \frac{1}{3} \times 4 \frac{4}{5} \\ = \frac{4}{3} \times \frac{24}{5} \\ = 4 \times \frac{8}{5} \\ = \frac{32}{5} \\ = 6 \frac{2}{5} [/tex]
