Answer 1

Resposta:

12% de 300= 36

25% de 1200= 300kg

8% de 75= 5,8 ou ≈6

2% de 250= R$5,00

Answer 2

Resposta:A) 12%/100% = x/300 -> 12.300 = 100x -> 3.600/100 = x -> x= 36 revistas. B) 25%/100% = x/1200-> 25.1200=100x -> 30000/100= x -> x = 300kg. C) 8%/100%= x/75 -> 8.75= 100x -> x= 6 gols. D) 2%/100%= x/250 -> 2.250=100x -> 500/100= x -> x= 5 .
