40% de 69= 40.69/100=2760/100=276/10=
=27,60
Se a mercadoria sofreu um desconto de 40%, então:
69-27,60=41,40

Com a regrinha de três na cabeça vc nunca mais vai esquecer: 100% - 69
40%- x ....100x =69.40.... x=69.40 , dividido por 100
RESUMINDO: 40 x 69, corta os dois zéros, digo, duas casas= resultado.

Conhece a regra de 3?

100% = 69
40% = x

Multiplica em cruz:
100 X x = 100x
40 X 69 = 2760
Agora divide (x na 1ª parte):
x=2760/100 = R\$27,60

Ou vai em qualquer calculadora e coloca:
69 - 40% = 27,6

69 x 0,40... É simples e o resultado é: 27,6...
Se for na calculadora pode fazer assim ou 69x40%... Dá no mesmo... a maioria das calculadoras tem o botão de porcentagem.

Boa Sorte!

De uma forma simples? É só multiplicar a taxa (40%) pelo capital (69 reais) e depois divide por 100.

40 X 69 = 2760
2760 / 100 = (conta duas casas da direita para a esquerda e coloca a vírgula.

2760 / 100 = 27,60

Logo: R\$ 27,60

(R\$)69,00 X (%)40 = 2760 (Conta 2 casas de traz pra frente e põe a virgula)

Vai dar R\$ 27,60

Valor total 69,00 - desconto 27,60 = 41,40

69,00 - 40% = 41,40

Pode fazer por regra de três:

69 reais ---- 100%
x ----------- 40%

x = 27,6 reais
