Question

4/3-1/3-2/3 8/5-10/5+1/5
1/7+2/7-17/7
3/5+2/5+8/5
2/6-1/6+3/6

Answer 1

Resposta:

$\frac{4}{3} -\frac{1}{3}-\frac{2}{3} = \frac{4-1-2}{3} = \frac{1}{3}\\\\ \frac{8}{5} - \frac{10}{5} + \frac{1}{5} = \frac{8-10+1}{5} = \frac{-1}{5} = - \frac{1}{5}\\\\ \frac{1}{7}+ \frac{2}{7}- \frac{17}{7} = \frac{1+2-17}{7} = \frac{-14}{7} = - \frac{14}{7}\\\\ \frac{3}{5}+ \frac{2}{5}- \frac{8}{5} = \frac{3+2+8}{5} = \frac{13}{5} \\\\ \frac{2}{6}- \frac{1}{6}+ \frac{3}{6} = \frac{2-1+3}{6} = \frac{4}{6}$
