Answer 1

a) 600/5= 120
b) 1500/2= 750     1500/4= 375   750+375= 1125
c)  2000+(2000/2)=2000+1000=3000

Answer 2

a) 20% de 600

20 . 600 = 100 . x
12.000 = 100x
12.000/100 = x
120 = x

b) 75% de 1.500

75 . 1.500 = 100 . x
112.500 = 100x
112.500/100 = x
1.125 = x

c) 150% de 2.000
150 . 2.000 = 100 . x
300.000 = 100x
300.000/100 = x
3.000 = x
