Oi

regra de três

a) 34% de 24,00

100%------24,00

34%------x

100x = 816

x = 816/100

x = 8,16

b) 24% de 89,00

100%-------89,00

24%-------x

100x = 2136

x = 2136/100

x = 21,36

c) 56% de 350,00

100%------350,00

56%-------x

100x = 19600

x = 19600/100

x = 196

d) 86 % DE 1200,00

100%--------1200

86%---------X

100X = 103200

X = 103200/100

X = 1.032
