Question

a) 12 % de 400
b) 5% de 6000
c) 2% de 5600
d) 15% de 890
e) 11% de 450
f) 95 % de 3820

Answer 1

A) 12% de 400;

12/100 = x/400

100x = 400 × 12

100x = 4.800

x = 4.800/100

x = 48.

B) 5% de 6.000;

5/100 = x/6.000

100x = 5 × 6.000

100x = 30.000

x = 30.000/100

x = 300.

C) 2% de 5.600;

2/100 = x/5.600

100x = 2 × 5.600

100x = 11.200

x = 11.200/100

x = 112.

D) 15% de 890;

15/100 = x/890

100x = 15 × 890

100x = 13.350

x = 13.350/100

x = 133.5

E) 11% de 450;

11/100 = x/450

100x = 11 × 450

100x = 4.950

x = 4.950/100

x = 49.5

F) 95% de 3.820;

95/100 = x/3.820

100x = 95 × 3.820

100x = 362.900

x = 362.900/100

x = 3.629
