Answer 1

A) $3\% \text{ de } 400 = \dfrac{3 \times 400}{100} = \dfrac{1200}{100} = 12$

B) $18\% \text{ de } 8600 = \dfrac{18 \times 8600}{100} = \dfrac{154800}{100} = 1548$

C) $35\% \text{ de } 42000 = \dfrac{35 \times 42000}{100} = \dfrac{1470000}{100} = 14700$

D) $0.5\% \text{ de } 150000 = \dfrac{0.5 \times 150000}{100} = \dfrac{75000}{100} = 750$

E) $1\% \text{ de } 3000 = \dfrac{1 \times 3000}{100} = \dfrac{3000}{100} = 30$

F) $120\% \text{ de } 6200 = \dfrac{120 \times 6200}{100} = \dfrac{744000}{100} = 7440$

G) $3.2\% \text{ de } 6000 = \dfrac{3.2 \times 6000}{100} = \dfrac{19200}{100} = 192$

H) $12.5\% \text{ de } 18000 = \dfrac{12.5 \times 18000}{100} = \dfrac{225000}{100} = 2250$

Answer 2

Resposta: a)3% x 400 = 3x 400/100= 12

b)18% x 8600= 18 x 8600/100= 86x18=1.548

c) 35% x 42000= 35x42000/100= 35x420= 14.700

d)0,5% x 150000= 0,5 x 1500= 750

e)1% x 300= 0,01 x 300= 3

f)120% x 6200= 120x62=7.440

g)3,2% x 6000= 3,2 x 60= 192

h)12,5% x 18000= 12,5 x 180= 2.250
