Answer 1

Resposta:

Olá!!!

Explicação passo-a-passo:

$a) (-2/5) + 3/2 = \\ \\ \frac{ - 4 + 15}{10} \\ \\ s = \frac{11}{10} </p><p>$

$b) (-5/6) + (-1/2) = \\ \\ \frac{ - 5 - 3}{6} \\ \\ \frac{ - 8}{6} \\ \\ - \frac{8}{6 } \\ \\ \\ s = - \frac{4}{3}$

$c) (8/7) – (34/7) = \\ \\ \frac{8 - 34}{7} \\ \\ \frac{ - 26}{7} \\ \\ \\ s = - \frac{26}{7}$

$d) (-2/5) + 3/2 = \\ \\ \frac{ - 4 + 15}{10} \\ \\ \\ s = \frac{11}{10}$

$e) (-1/6) + (-1/2) = \\ \\ \frac{ - 1 - 3}{6} \\ \\ \frac{ - 4}{6} \\ \\ - \frac{4}{6} \\ \\ s = - \frac{2}{3} </p><p>$

$f) (9/3) – (16/3) = \\ \\ \frac{ 9- 16}{3} \\ \\ \frac{ - 7}{3} \\ \\ \\ s = - \frac{7}{3}$

espero ter ajudado!!
