1) Alternativa (B)

$\frac{1}{6} + \frac{1}{6} + \frac{1}{6} \\ \\ \frac{ 3 }{6} \div 3 = \frac{1}{2}$

2) Alternativa (C)

$( \frac{7}{8} + \frac{13}{8} ) - \frac{3}{4} \times \frac{4}{2} + 9 \\ \\ \frac{20}{8} - \frac{12}{8} + 9 \\ \\ \frac{8}{8} + \frac{9}{1} \\ \\ \frac{8 + 72}{8} \\ \\ \frac{80}{8} = 10$
