Va rog frumos este urgent!​

Answer 1

Răspuns:

Explicație pas cu pas:

108*p/100 = 6

p = 100*6/108 = 5,(5)

_______________

50*p/100 = 80

p = 100*80/50 = 160

_______________

400*p/100 = 20

p = 100*20/400 = 5

_______________

16*p/100 = 4

p = 4*100/16 = 25

______________

300*p/100 = 12

p = 100*12/300 = 4

Answer 2

a) p/100×108=6

27p/25=6

27p=6×25

27p=150

P=150:27

P=5,(5)

b) p/100×50=80

p/2=80

p=2×80

p=160

c) p/100×400=20

4p=20

p=20:4

p=5

d)p/100×16=4

4p/25=4

4p=25×4

p=100:4

p=25

e) p/100×300=12

3p=12

p=12:3

p=4
