Answer 1

a) 6% de 100

100x = 6.100

100x = 600

x = 600/100

x = 6

b) 70% de 100

100x = 70.100

100x = 7000

x = 7000/100

x = 70

c) 30% de 50

100x = 30.50

100x = 1500

x = 1500/100

x = 15

d) 20 % de 60

100x = 20.60

100x = 1200

x = 1200/100

x = 12

e) 25% de 200

100x = 25.200

100x = 5000

x = 5000/100

x = 50

f) 7,5% de 400

100x = 7,5.400

100x = 3000

x = 3000/100

x = 30

g) 42% de 300

100x = 42.300

100x = 12600

x = 12600/100

x = 126

h) 10% de 62,5

100x = 10.62,5

100x = 625

x = 625/100

x = 6,25​
