Answer 2

Oi....

Calcule:  

a)

5% de 310

100%---------310

5%-------------x

100x = 5.310

100x = 1550

x = 1550/100

x = 15,5

b)

10% de 250

100%---------250

10%-----------x

100x = 10.250

100x = 2500

x = 2500/100

x = 25

c)

9% de 115

100%--------115

9%-----------x

100x = 9.115

100x = 1035

x = 1035/100

x = 10,35
