Resolução.

a)

20% de 200

100x = 20.200

100x = 4000

x = 4000/100

x = 40

b)

10% de 800

100x = 10.800

100x = 8000

x = 8000/100

x = 80

c)

30% de 90

100x = 30.90

100x = 2700

x = 2700/100

x = 27

d)

75% de 40

100x = 75.40

100x = 3000

x = 3000/100

x = 30

e)

40% de 150

100x = 40.150

100x = 6000

x = 6000/100

x = 60

f)

50% de 70

100x = 50.70

100x = 3500

x = 3500/100

x = 35

g)

5% de 60*

100x = 5.60

100x = 300

x = 300/100

x = 3

h)

35% de 300

100x = 35.300

100x = 10500

x = 10500/100

x = 105

i)

17% de 100

100x = 17.100

100x = 1700

x = 1700/100

x = 17

j)

8% de 50

100x = 8.50

100x = 400

x = 400/100

x = 4

k)

30% de 600

100x = 30.600

100x = 18000

x = 18000/100

x = 180

l)

50% de 900

100x = 50.900

100x = 45000

x = 45000/100

x = 450

m)

20% de 300

100x = 10.300

100x = 3000

x = 3000/100

x = 30

n)

15% de 120

100x = 15.120

100x = 1800

x = 1800/100

x = 18

o)

35% de 400

100x = 35.400

100x = 14000

x = 14000/100

x = 140​

Bons estudos.

Answer 2
