Respuesta:
[tex] = - \frac{7}{5} [/tex]
Explicación paso a paso:
[tex] = - \frac{2}{5} - \frac{12}{27} \div \frac{4}{9} [/tex]
[tex] = - \frac{2}{5} - 1[/tex]
[tex] = - \frac{1 \times 5}{5} - \frac{2}{5} [/tex]
[tex] = \frac{ - 1 \times 5 - 2}{5} [/tex]
[tex] - 1 \times 5 - 2 = - 7[/tex]
[tex] = - \frac{7}{5} [/tex]
