Question

$\frac{2}{5}- \frac{1}{2}(4- \frac{4}{5})/6$

Answer 1

RESOLVER:

$\frac{2}{5}-\frac{\frac{1}{2}\cdot \left(4-\frac{4}{5}\right)}{6}$
$\frac{2}{5}-\frac{\frac{1}{2}\left( \frac{16}{5} \right)}{6}$
$\frac{2}{5}-\frac{\left( \frac{8}{5} )}{6}$
$\frac{2}{5}- \frac{4}{15}$
$\frac{2\cdot \:3}{15}-\frac{4}{15}$
$\frac{2\cdot \:3-4}{15}$
$\frac{2}{15}$
