A)
[tex]( - \frac{9}{16}) \div ( + \frac{45}{8} ) = - \frac{9}{16} \div \frac{45}{8} = - \frac{9}{16} \times \frac{8}{45} - \ \frac{9 \times 8}{16 \times 45} - \frac{75}{720} - \frac{ - 1}{10} [/tex]
B)
[tex]( \frac{6}{17} ) \div ( - \frac{12}{34} ) \: \: \: \frac{6}{17} \div - \frac{6}{17} \frac{6}{17} \times \frac{17}{ - 6} 6 \times \frac{1}{ - 6} = - 1[/tex]
