AULA DA SEMANA
Existe o n&uacut=
e;mero
30%?
Na verdade, 30%
é um símbolo utilizado pela matemática para representar
0,30, ou seja, matematicamente falando não existe o número
30%.
Por que 0,30 e
não 30%?
A porcentagem é calculada sempre com base em 100.
Isso quer dizer que o número 1 tem o mesmo peso do número 100.
Então:
![](3D"aula1_arquivos/image002.gif")
Lê-se=
: Um está para Cem e X está para Tri=
nta.
Para resolver esse problema usa-se a regra de três=
, ou
seja, multiplicação em cruz.
![](3D"aula1_arquivos/image004.gif")
Atenç&ati=
lde;o: O número 100 está sendo multiplicad=
o por X e o número 30 está do outro lado do s=
inal
de igual. A primeira coisa a fazer é isolar X. Como o
número 100 está =
sendo
multiplicado por X e o mesmo p=
recisa
ser transferido para o outro lado do sinal de igual, o número 100 se tornará divisor do
dividendo número 30.
Então:
![](3D"aula1_arquivos/image006.gif")
Não é possível fazer a conta tendo o
dividendo menor do que o divisor, a menos que seja emprestado um zero para o
dividendo. Então:
![](3D"aula1_arquivos/image008.gif")
Para manter a proporção, sabendo que um ze=
ro
foi emprestado para o dividendo, outro zero acompanhado de vírgula
deverá ser colocado no cociente antes de iniciar a
multiplicação. Então:
0,30
O número 3 representa a multiplicaçã=
;o
com o número 100 e o número 0 final representa o resto da
divisão.
Observaç&=
atilde;o: Essa regra é vá=
lida
para todos os casos envolvendo porcentagem.
EXERCÍCIO=
Um produto com 30% de desconto custa R$100,00. Se o mesmo
não tivesse redução de preço, por quanto seria
vendido?
