Answer 1

[tex]- \frac{1}{4} : \frac{3}{8} = -\frac{1}{4} * \frac{8}{3} = - \frac{8}{12} = - \frac{2}{3} \\\\ - \frac{4}{3} : (- \frac{5}{9}) = \frac{4}{3} * \frac{9}{5} = \frac{36}{15} = \frac{12}{5} \\\\ 0:(- \frac{7}{3}) = 0 [/tex]

Answer 2

(-1supra4) ori 8supra3=-2 supra 3
(-4supra3) ori(-9supra5)=12 supra5
0  ori (-3supra7)=0
