Answer 1

a) 10% de 80= 8
10%+10%=20%, logo 8+8=16

b) 10% de 300= 30
1% de 300= 3
10%+1%+1%=12%, logo 30+3+3=36

c) 10% de 90= 9
5% de 90= 4,5
10%+5%= 15%, logo 9+4,5= 13,5

d) 50% de 40= 20
50% dividido por 2= 25%, logo 20/2= 10

e) 10% de 240= 24
10%•8=80%, logo 24•8= 192

f) 50% de 1200= 600
25% de 1200= 300
50%+25%= 75%, logo 600+300= 900
