/Răspuns:
Tudor +Dan+Mihai=110lei
110:3= 36, 6 ( cat are un copil)
36 , 6 =Tudor⇒
36 ,6 : 2 = 18 ,3 (cat are Dan )
18 ori 1/3 =36 lei mihai
t-Tudor
d-Dan
m-Mihai
t+d+m=110
d=t÷2=>t=d×2
m=t÷3=>t=m×3
----------------------------,---
t,d,m=?
---------------------------,,---
t+t/2+t/3=110
t×6+(t/2×3)+(t/3)×2=110×6
6t+3t+2t=660
11t=660
t=660÷11
t=60
d=t÷2
d=60÷2
d=30
m=t÷3
m=60÷3
m=20
V:60+30+20=110
V:90+20=110
