Ana=x baloane A) |____|____|____|____|
Dan=x:4 B) |____|
---------------------- .--------------------------------------
A+B=? 4+1=5=> A+D=5 baioane
A-B=?
A=4*1
A=4 baloane
D=4:4
D=1 balon
A+D=4+1
A+D=5 baloane
A-D=4-1
A-D=3baloane
Oricate baloane ar avea Ana,Dan are de 4 ori mai putine baloane si invers ....oricate baloane ar avea Dan,Ana are de 4 ori mai multe decat el.
ex....:A=8....=>D=2....(8:4=2)
A=12..=>D=3....(12:4=3)
sau...D=5..=>A=20....(5*4=20)
D=4..=>A=16....(4*4=16)
etc.............
