Question

Rosu-imparat are nevoie de 360 de osteni pt a se lupta cu 8 zmei.daca zmeii ar fi cu 24% mai putini,cati osteni ar trebuii?

Answer 1

8 z........100%
x..................100-24=76%
x=76*8:100= 6,08 ≈ 6 z


360 o....................8 z
x............................6

x=360*6:8= 270 o

o=osteni
z= zmei

Answer 2

$24\% \ din \ 8 = \frac{\not 24}{\not 100}*8= \frac{6}{25}*8 \to \frac{48}{25} \\\\ 8^{(25}-\frac{48}{25} = \frac{200-48}{25} \to \frac{152}{25} \to 6,08 \approx 6 \ zmei \\\\\\ 360 \ osteni........8 \ zmei \\ x ......................6 \ zmei \\\\\\ x= \frac{360*6}{8} \\\\ x=45*6 \\\\ \boxed{x=270 \ osteni}$
