A)25% de 200:
B)15% de 50:
C)6% de 54:
D)21% de 35:
E)2% de 13:

Answer 1

a) 25% de 200: 25/100 x 200 = (25 x 200)/100 = 25  x 2 = 50

b) 15% de 50: 15/100 x 50 = (15 x 50)/100 = 750/100= 7,5

c) 6% de 54: 6/100 x 54 = (6 x 54)/100 = 324/100 = 3,24

d) 21% de 35: 21/100 x 35 = (21 x 35)/100 = 735/100 = 7,35

e) 2% de 13: 2/100 x 13 = (2 x 13)100 = 26/100 = 0,26

Espero ter ajudado.
