H) 560

I) 630

J) 700

Explicação passo a passo:

Fazemos uma regra de 3 simples:

a)

700 = 100

x = 10

100x = 700 . 10

100x = 7000

x = 7000/100

x = 70

b)

700 = 100

x = 20

100x = 700 . 20

100x = 14000

x = 14000/100

x = 140

c)

700 = 100

x = 30

100x = 700 . 30

100x = 21000

x = 21000/100

x = 210

d)

700 = 100

x = 40

100x = 700 . 40

100x = 28000

x = 28000/100

x = 280

e)

700 = 100

x = 50

100x = 700 . 50

100x = 35000

x = 35000/100

x = 350

f)

700 = 100

x = 60

100x = 700 . 60

100x = 42000

x = 42000/100

x = 420

g)

700 = 100

x = 70

100x = 700 . 70

100x = 49000

x = 49000/100

x = 490

h)

700 = 100

x = 80

100x = 700 . 80

100x = 56000

x = 56000/100

x = 560

i)

700 = 100

x = 90

100x = 700 . 90

100x = 63000

x = 63000/100

x = 630

j)

700 = 100

x = 100

100x = 700 . 100

100x = 70000

x = 70000/100

x = 700
