25% din 50
50% din 40
75% din 200
p% din 80=120

Answer 1

25%din50=25/100 din 50 = 1/4 din 50 = 50/4=12,5

25%din50=(25/100)*50=(1/4)*50=50/4=12,5
50%din40=(50/100)*40=(1/2)*40=40/2=20
75%din200=(75/100)*200=(3/4)*200=(3*200)/4=600/4=150
p%din80=120 rescriem (p/100)*80=80*p/100 =>80p/100=120 => 80p=100*120=>80p=12000 => p=12000/80=1200/8=600/4=300/2=150 deci p=150, rescris inseamna 150%din80=120
