Question

O resultado da expressão é: a -3/6
b 1/2
c 5/6
d 1/3

Answer 1

Resposta:

1/2

Explicação passo-a-passo:

5/2 + [2-(8/3+4/3)

5/2 + [2- 12/3] =>  2/1 - 12/3 => 6-12 (tudo dividido por 3)

5/2 - 6/3 => 15-12 => (tudo dividido por 6)

3/6 => simplificando 1/2

Answer 2

$\mathsf{\dfrac{5}{2}+\left[2-\left(\dfrac{8}{3}+\dfrac{4}{3}\right)\right]}\\\mathsf{\dfrac{5}{2}+\left[2-\dfrac{8}{3}-\dfrac{4}{3}\right]}\\\mathsf{\dfrac{5}{2}+2-\dfrac{8}{3}-\dfrac{4}{3}}\\\mathsf{\dfrac{15+12-16-8}{6}=\dfrac{3\div3}{6\div3}}\\\large\boxed{\boxed{\boxed{\boxed{\mathsf{\dfrac{1}{2}}}}}}$
