Metoda I ( metoda figurativa sau grafica )
I / --- / --- / --- / --- / --- /
II / --- /
III / --- / --- / --- / --- /
5 + 1 + 4 = 6 + 4 = 10 ( segmente egale )
∅ Rezolvare : 60 : 10 = 6 ( reprezinta un segment , al doilea numar )
6 · 5 = 30 ( primul număr )
6 · 4 = 24 ( al treilea numar )
∅ Răspuns : I — 30 ; II — 6 ; III — 24 .
