3 cornuri....5 pâini....2300 g | × 2
4 cornuri....2 pâini....1200 g | × 5
6 cornuri....10 pâini....4600 g
20 cornuri....10 pâini....6000 g
14 cornuri......-----------.....1400 g
1 corn....1400 : 14 = 100 g
3 × 100 = 300 g....5 pâini....2300 g
5 pâini....2300 - 300 = 2000 g
1 pâine.....2000 : 5 = 400 g
1 corn + 1 pâine = 100 g + 400 g = 500 g
