Question

qual o valor de 20% e 40% de R$ 68,00 ?

Answer 1

20% = 20 x 68 = 1360/100 = 13,60 Reais

40 % = 40 x 68 = 2720 / 100 = 27,2 reais

Answer 2

68,00 - 100%
x       -  20%
100x = 1360
x = 1360/100
x = R$ 13,60
20% de R$ 68,00 = R$ 13,60

68,00 - 100%
x       -   40%
100x = 2720
x = 2720/100
x = R$ 27,20
40% de R$ 68,00 = R$ 27,20
