Question

1.-el 80% de 75 % de 100% de 30 es :
2.-el 50 %del 20% del 100% de 30 es:
3.-el 200% de 2% del 4% de 180000 es :

Answer 1

1.-
80% = 80/100 = 0.8
75% = 75/100 = 0.75
100% = 100/100 = 1
1*0.75*0.8*30 = 18

2.-
50% = 50/100 = 0.5
20% = 20/100 = 0.2
100% = 100/100 = 1
1*0.2*0.5*30 = 3

3.-
200% = 200/100 = 2
2% = 2/100 = 0.02
4% = 4/100 = 0.04
0.04*0.02*2*180000 = 288


Saludos.......

Answer 2

1. 80/100x 75/100 x 100/100x30
4/5 x 3/4 x 1 x 30
...simplificando saldría 18

2.50/100 x 20/100 x 100/100 x 30
...1/2 x 1/5 x 1 x 30
simplificando saldría 3

3. 200/100 x 2/100 x 4/100 x 180000
......2 x 1/50 x 4 /25 x 180000
simplificando saldría 288
