Answer 2

Explicación paso a paso:

$\frac{1}{5} - \frac{2}{5} = \frac{1}{5} \\ \frac{15}{14} + \frac{13}{14} = \frac{28}{14} = \frac{4}{2} = \frac{2}{1} =2 \\ \frac{13}{2} - \frac{31}{2} = \frac{ - 18}{2} = \frac{ - 9}{1} =-9 \\ \frac{11}{7} + \frac{23}{7} = \frac{34}{7}$

$\frac{3}{2} - \frac{9}{2 } = \frac{ - 6}{2} = \frac{ - 3}{1} = - 3 \\ \frac{1}{6} + \frac{2}{6} + \frac{3}{6} = \frac{6}{6} = 1 \\ \frac{40}{5} + \frac{10}{5} - \frac{5}{5} = \frac{45}{5} = \frac{9}{1} = 9 \\ - \frac{3}{9} + \frac{3}{9} = 0$
