Question

X supra 3 = y supra 2 = z supra 4
X*y*z = 192
X, y, z =?

Answer 1

Fiecare raport il egalam cu k
$\frac{x}{3}$ = k = x= 3* k
$\frac{y}{2}$ = k = y= 2*k
$\frac{z}{4}$ = k = z= 4*k
Inlocum in inmultire
3k*2k*4k=192
24k=192
k=192 : 24
k=8
Si acum inlocuim k cu 8
x= 3* 8= 24
y=2*8= 16
z=4*8= 32
x= 24
y=16
z=32
