Answer 1

Resposta:

$\boxed{\bf{\dfrac{1}{9}}}$

Explicação passo-a-passo:

Vamos resolver a expressão:

$\left(\dfrac{2}{3}+\dfrac{1}{4}\times\dfrac{2}{3}\right):\left(5\times\dfrac{3}{2}\right)\\\\\\\left(\dfrac{2}{3}+\dfrac{2}{12}\right):\left(\dfrac{15}{2}\right)\\\\\\\left(\dfrac{8+2}{12}\right):\left(\dfrac{15}{2}\right)\\\\\\\dfrac{10}{12}:\dfrac{15}{2}=\dfrac{10}{12}\times\dfrac{2}{15}=\dfrac{\not{10}^2}{\not{12}^6}\times\dfrac{\not{2}^1}{\not{15}^3}=\dfrac{2}{18}=\boxed{\bf{\dfrac{1}{9}}}$
