Answer 1

Resposta:

ITEM (A)

Explicação passo-a-passo:

$\frac{3 \times {( - \frac{1}{2} )}^{2} + \frac{1}{4} }{3 \times {( - \frac{1}{3} )}^{2} - \frac{3}{2} }$

$\frac{3 \times {( \frac{1}{2} )}^{2} + \frac{1}{4} }{3 \times {( \frac{1}{3} )}^{2} - \frac{3}{2} }$

$\frac{3 \times \frac{1}{4} + \frac{1}{4} }{3 \times \frac{1}{9} - \frac{3}{2} }$

$\frac{ \frac{3}{4} + \frac{1}{4} }{ \frac{1}{3} - \frac{3}{2} }$

$\frac{1}{ \frac{1}{3} - \frac{3}{2} }$

$\frac{1}{ - \frac{7}{6} }$

$- \frac{1}{ \frac{7}{6} }$

$1 \div \frac{7}{6}$

$1 \times \frac{6}{7}$

$\frac{1 \times 6}{7}$

$- \frac{6}{7}$
