1) Determine mentalmente os resultados de 1%, 5%, 10% e 50% dos valores a seguir:

• 50 • 200 • 350 • 500

Explicação passo-a-passo:

50

1% =  0.5

5% = 2,5

10% = 5

50% = 25

200

1% =  2

5% = 10

10% = 20

50% = 100

350

1% =  3.5

5% = 17,5

10% = 35

50% = 175  

500

1% =  5

5% = 25

10% = 50

50% = 250

Answer 2

Oi...

a) 1% de 50

100%------50

1%-----------x

100x = 50

x = 50/100

x = 0,5

5% de 50

100%-----------50

5%---------------x

100x = 250

x = 250/100

x = 2,5

10% de 50

100%----------50

10%-------------x

100x = 500

x = 500/100

x = 5

50% de 50

100%----------50

50%-----------x

100x = 2500

x = 2500/100

x = 25

b) 1% de 200

100x = 200

x = 200/100

x = 2

5% de 200

100x = 1000

x = 1000/100

x = 10

10% de 200

100x = 2000

x = 2000/100

x = 20

50% de 200

100x = 10000

x = 10000/100

x = 100

c) 1% de 350

100x = 350

x = 350/100

x = 3,5

5% de 350

100x = 1750

x = 1750/100

x = 17,5

10% de 350

100x = 3500

x = 3500/100

x = 35

50% de 350

100x = 17500

x = 17500/100

x = 175

d) 1% de 500

100x = 500

x = 500/100

x = 5

5% de 500

100x = 2500

x = 2500/100

x = 25

10% de 500

100x = 5000

x = 5000/100

x = 50

50% de 500

100x = 25000

x = 25000/100

x = 250
