Answer 2

Olá....

Resolução:

1) 29% de 40

100x = 29.40

100x =1160

x = 1160/100

x = 11,6

2) 10% de 92

100x = 10.92

100x = 920

x = 920/100

x = 9,2

3) 5% de 100

100x = 5.100

100x = 500

x = 500/100

x = 5

4) 12% de 60

100x = 12.60

100x = 720

x = 720/100

x = 7,2

5) 3% de 54

100x = 3.54

100x = 162

x = 162/100

x = 1,62

6) 37% de 88

100x = 37.88

100x = 3256

x = 3256/100

x = 32,56
