{1/3 *[(7*3 – 1/2 ) : 35/23]}
o resultado é:
a) 20/3
b) 1/3
c) 41/9
d) 4/9
e) nda
Entao é assim
{ 1/3*[(7*3 - 1/2) : 35/23]}
{ 1/3*[( 21-1/2 ): 35/23]}
{1/3 *[43/6 : 35/23]} =
{1/3 * 41/2 * 23/35 }
{ 1/3* 943/70 = 943/210 = 41/10 nao tem opcao serta. E) nda
{ 1/3*[( 21-0,5 ): 35/23]}
{1/3 *[20,5 ; 35/23]} =
{ 1/3 * 20,5;35/23 }
{ 1/3* 41*23/2*35
{ 1/3* 943/70 = 943/210 = 4,49 ~~ nenhuma delas
Resposta: e)
