Answer 1

Răspuns:

il scriem pe 1,(5) ca fractie si o sa avem 15-1/10= 14/10

$\frac{14}{10} - \frac{1}{16} \times ( \frac{9}{10} - \frac{1}{10} \times 1)$

$\frac{14}{10} - \frac{1}{16} \times ( \frac{9}{10} - \frac{1}{10} ) \\ \\ \frac{14}{10 } - \frac{1}{16} \times \frac{8}{10} \\ \\ \frac{14}{10} - \frac{2}{20} \\ = \frac{14}{10} - \frac{1}{10} = \frac{13}{10}$
