X/1/10=Y/2/10=Z/3/10=k rezulta
X=1/10(ori)k
Y=2/10(ori)k
Z=3/10(ori)k
3x1/10k+2x2/10k+5x3/10k=110
3/10k+4/10k+15/10k=110
22/10k=110
K=110/1:22/10
K=110/1 ori 10/22(se simplifica 110 cu 22 si in loc de 22 ramane 1 si in loc de 110 ramane 5)
K=5 ori 10
K=50
X=1/10 ori 50
X=5
Y=2/10 ori 50
Y=10
Z=3/10 ori 50
Z=15
