3,5% de R$ 20000,00​

Answer 1

Resposta:

6% de 300= 18

14% de 2100= 294

45% de 8200= 3690

2% de R%150,00= R$3,00

18% de R$6000,00= R$1080,00

3,5% de R$20000,00= R$700,00

Answer 2

Resposta:

X =6%

300= 100%

meio pelos extremos / regra de três

100x= 1,800

x=1,800/100 =18

X=14%

2100=100%

100x=29,400

x=29,400/100 =294

X=45%

8,200=100%

100x=369,000

x=369,000/100=3,690

X=2%

150=100%

100x= 300

x=300/100= R$ 3

X=18%

6000 =100%

100x= 108,000

x=108,000/100= R$ 1,080

X=3,5%

20,000=100%

100x=70,000

x=70,000/100 =700
