Answer 1

Espero ter ajudado :)

Resposta:

A) $\frac{13x}{2}$

B)  $\frac{1}{8}$

Explicação passo-a-passo:

A)

$3x\left(1\frac{2}{3}+\frac{1}{2}\right)\\\\3x\left(\frac{5}{3}+\frac{1}{2}\right)\\\\=3\cdot \frac{13}{6}x\\\\=\frac{13\cdot \:3x}{6}\\\\=\frac{39x}{6}\\\\=\frac{13x}{2}$

B)

$\left(1\frac{1}{4}-\frac{1}{8}\right)\div \:9\\\\\left(\frac{5}{4}-\frac{1}{8}\right)\div \:9\\\\=\frac{\frac{9}{8}}{9}\\\\=\frac{9}{8\cdot \:9}\\\\=\frac{9}{72}\\\\=\frac{1}{8}$
