Metoda mersului invers cu reprezentare grafica
l------------------l-----------------l------------------l → garoafe
[__________][__________]l----l----l----l----l → restul = 4/4
dimineata pranz [_______] +9 garoafe au ramas
seara = 3/4
3 × 9 = 27 garoafe a vandut seara
27 + 9 = 36 garoafe a vandut la pranz
36 garoafe a vandut si dimineata
36 + 36 + 27 + 9 = 108 garoafe a avut florareasa
