360 lei _____ 100%

x lei _______ p%

x = 360p/100 = 36p/10 = 18p/5

18p/5 _______ 100%

243 lei ______ 75%

24300 = 18p•15

p=24300/270=2430/27

p=90


Exploa112: pai daca p este 90% de unde mai urmeaza inca 25% reducere?
iakabcristina2: Nu reducerea e de 90%
iakabcristina2: E procentul rămas după reducere. Adică 90%. Reducerea e de 10%
