Answer 1

$\frac{1}{3} + \frac{5}{6} = \frac{2}{6} + \frac{5}{6} = \frac{7}{6} =1 \frac{1}{6}$
$\frac{5}{7} - \frac{1}{14} = \frac{10}{14} - \frac{1}{14} = \frac{9}{14}$
$- 5 \frac{1}{3} \times 1 \frac{1}{2} = - \frac{16 \times 3}{3 \times 2} = - 8$
$- \frac{4}{5} \div ( - 1 \frac{1}{15} ) = \frac{4 \times 15}{5 \times 16} = \frac{3}{4}$
