Answer 2

Respuesta:

a.

$\frac{1}{3} - \frac{2}{3} + \frac{1}{4} = \frac{4 - 8 + 3}{12} = - \frac{1}{12}$

b.

$\frac{2}{6} - \frac{4}{2} + \frac{5}{3} = \frac{2 - 12 + 10}{6} = \frac{0}{6} = 0$

c.

$4 - \frac{2}{5} + \frac{2}{6} = \frac{120 - 12 + 10}{30} = \frac{118}{30} = \frac{59}{15}$

d.

$\frac{7}{8} - \frac{1}{3} + \frac{2}{7} = \frac{147 - 56 + 48}{168} = \frac{139}{168}$
