eu precisava da conta montada se puder ajudar ​

Answer 1

1) 150 = 100%

      x = 40%

100x = 150 . 40

100x = 6000

     x = 6000 : 100

     x = 60

b) 70 = 100%

      x = 50%

100x = 70 . 50

100x = 3500

     x = 3500 : 100

     x = 35

c) 50 = 100%

      x = 8%

100x = 50 . 8

100x = 400

     x = 400 : 100

     x = 4

d) 600 = 100%

        x = 30%

100x = 600 . 30

100x = 18000

     x = 18000 : 100

     x = 180

e) 900 = 100%

        x = 50%

100x = 900 . 50

100x = 45000

     x = 45000 : 100

     x = 450

f) 300 = 100%

       x = 20%

100x = 300 . 20

100x = 6000

     x = 6000 : 100

     x = 60

g) 120 = 100%

        x = 15%

100x = 120 . 15

100x = 1800

     x = 1800 : 100

     x = 18

h) 400 = 100%

        x = 35%

100x = 400 . 35

100x = 14000

     x = 14000 : 100

     x = 140
