Salut !!
[tex]a) \: \frac{ \frac{2}{9} }{ - \frac { 5}{3} } = \frac{2}{9} \times \frac{ - 3}{5} = \frac{ - 6}{45} = \frac{ - 2}{15} [/tex]
[tex]b) \: \frac{ \frac{3}{5} }{ \frac{1}{5} } = \frac{3}{5} \times 5 = \frac{15}{5 } = 3[/tex]
[tex]c) \frac{ - \frac{1}{4} }{3} = - \frac{1}{4} \times \frac{1}{3} = - \frac{1}{12} [/tex]
[tex]d) \frac{ \frac{22}{7} }{ - 11} = \frac{22}{7} \times ( - \frac{1}{11} ) = -\frac{22}{77} [/tex]
=> -2/7
