Answer 1

Se trata de obtener los Porcentajes indicados de cada cifra proporcionada:

a) 40% de 25 =  

25 → 100%

X → 40%

X = (25 x 40%)/100%

X = 1.000/100

X = 10

b) 30% de 30 =  

30 → 100%

X → 30%

X = (30 x 30%)/100%

X = 900/100

X = 9

c) 20% de 50 =  

50 → 100%

X → 20%

X = (50 x 20%)/100%

X = 1.000/100

X = 10

d) 80% de 700 =  

700 → 100%

X → 80%

X = (700 x 80%)/100%

X = 56.000/100

X = 560

e) 75% de 250 =  

250 → 100%

X → 75%

X = (250 x75%)/100%

X = 18.750/100

X = 187,5

f) 65% de 100 =  

100 → 100%

X → 65%

X = (100 x 65%)/100%

X = 6.500/100

X = 65

g) 35% de 84 =  

84 → 100%

X → 35%

X = (84 x 35%)/100%

X = 2.940/100

X = 29,4

h) 25% de 90 =  

90 → 100%

X → 25%

X = (90 x 25%)/100%

X = 2.250/100

X = 22,5

i) 90% de 20 =  

20 → 100%

X → 90%

X = (20 x 90%)/100%

X = 1.800/100

X = 18

j) 85% de 150

150 → 100%

X → 85%

X = (150 x 85%)/100%

X = 12.750/100

X = 127,5
