Answer 1

Olá !

Resolução :

$\mathsf{ Media =\dfrac{\dfrac{1}{4}~~+~~\dfrac{1}{2}}{2}}} \\\\\\ \mathsf{Media =\dfrac{\dfrac{2 + 4}{8}}{2}}} \\\\\\ \mathsf{Media =\dfrac{\dfrac{6}{8}}{2}}} \\\\\\ \mathsf{Media =\dfrac{\dfrac{6}{8}}{\dfrac{2}{1}}} \\\\\\ \mathsf{Media =\dfrac{6}{8}\cdot\dfrac{1}{2}} \\\\\\ \mathsf{Media =\dfrac{6}{16}}$

Simplifica :

$\mathsf{\dfrac{6}{16}\div\dfrac{2}{2} =\dfrac{3}{8}}$

Resposta :

$\mathsf{Media =\dfrac{3}{8}}$
