Answer 1

$| \frac{1}{12} | + | \frac{5}{12} | = \frac{6}{12} = \frac{1}{2}$
$| \frac{1}{12} | + | - \frac{5}{12} | = | \frac{6}{12} | = \frac{1}{2}$
$| - \frac{4}{15} | + | - \frac{1}{15} | = \frac{6}{15} = \frac{2}{5}$
$| - \frac{9}{14} | - | \frac{3}{14} | = \frac{6}{14} = \frac{3}{7}$
$| 1\frac{2}{5} | + | - 1\frac{1}{5} | = 2\frac{3}{5}$
$| - 2 \frac{4}{7} | - | - 1\frac{3}{7} | =1 \frac{1}{7}$
