Answer 2

Salut,

$\frac{1}{2} \div \frac{3}{9} - 2.5 = \\ \\ \frac{1}{2} \div \frac{3}{9} - \frac{25}{10} = \\ \\ \frac{1}{2} \times \frac{9}{3} - \frac{25}{10} = \\ \\ \frac{9}{6} - \frac{25}{10} = > \frac{^{5)}25 }{10} = \\ \\ \frac{9}{6} - \frac{5}{2} = > \: numitor \: comun \: = 6 \\ \\ \frac{9^{(1} }{6} - \frac{5^{(3} }{6} = \\ \\ \frac{9}{6} - \frac{15}{6} = \\ \\ \frac{ - \: 6}{6} = > - 1$
