O=oile
m=mieii
o+m=170
3/5o=6/7m
3o·7=6m·5
21o=30m
o=30m/21 simplificam cu 3
o=10m/7
10m/7+m=170 amplificam cu 7 si eliminam numitorul
10m+7m=1190
17m=1190
m=70 miei
o+70=170
o=170-70
o=100 oi

O + m = 170
3o/5 = 6m/7
-----------------
3o = 30m/7 => o = 10m/7
10m + 7m = 1190 => m = 1190/17 = 70 => o = 100
