100%----------352

35%----------x

100.x = 35.352

100x = 12.320

x = 12.320/100

x = 123,2

55% de R$ 90,00 = 49,5

100%----------90,00

55%----------x

100.x = 55.90,00

100x =4.950

x = 4.950/100

x = 49,5

63% de R$ 1.229,00 = 774,27

100%---------1.229,00

63%----------x

100.x = 63. 1.229

100x = 77.427

x = 77.427/100

x = 774,27
