Question

2. Calcule as porcentagens abaixo:
a) 2 % de 700.
b) 30 % de 1.200.
c) 15 % de 450.
d) 72% de 1.800.​

Answer 1

Resposta:

a) 2% de 700

2 x 700 = 1400

1400 / 100 = 14

b) 30% de 1200

30 x 1200 = 36000

36000 / 100 = 360

c) 15% de 450

15 x 450 = 6750

6750 / 100 = 67,5

d) 72% de 1800

72 x 1800 = 129600

129600 / 100 = 1296

Answer 2

a) 2 % de 700

2% = 2 : 100 = 0.02

0.02 × 700 = 14

b) 30 % de 1.200.

30% = 30 : 100 = 0.3

0.3 × 1.200 = 360

c) 15 % de 450.

15% = 15 : 100 = 0.15

0.15 × 450 = 67.5

d) 72% de 1.800.

72% = 72 : 100 = 0.72

0.72 × 1.800 = 1.296
