Answer 1

Explicação passo-a-passo:

1)

100% ————— 350

1% ——————— x

100x = 1.350

100x = 350

x = 350/100

x = 3,50

b)

100% ————— 35

4% ——————— x

100x = 4.35

100x = 140

x = 140/100

x = 1,40

c)

100% ————— 1400

10% —————— x

100x = 10.1400

100x = 14000

x = 14000/100

x = 140 eleitores

d)

100% ————— 1400

15% —————— x

100x = 15.1400

100x = 21000

x = 21000/100

x = 210 eleitores

e)

100% ————— 3450

20% —————— x

100x = 20.3450

100x = 69000

x = 69000/100

x = 690 litros

f)

100% ————— 48

25% —————— x

100x = 25.48

100x = 1200

x = 1200/100

x = 12 carros
