78-3=75 Segmente egale
75:5=15 Trandafirii
15×2=30 Crinii
30+3=33 Garoafe. 15+
Proba:15+30+33=78 30
33
=
78
Răspuns:
78 FLORI IN TOTAL
CRIN =X
TRANDAFIRI =2X
GAROAFE =3X
DECI 78 =X+2X+3X =6X
X=78 : 6 =13
X= 13 CRINI
TRANDAFIRI =2X13 =26
GAROAFE =3X13 = 39
VERIVICARE: 13 CRINI+ 26 TRANDAFIRI + 39 GAROAFE = 78 FLORI
