Answer 2

Ex 12

3 cornuri.......5 pâini.......2300 g | × 4

4 cornuri........2 pâini.......1200 g | × 3


12 cornuri......20 pâini.....9200 g

12 cornuri.......6 pâini......3600 g

--------------........14 pâini.......5600 g

1 pâine......5600 : 14 = 400 g


3 cornuri.......5 × 400 = 2000 g.....2300 g

3 cornuri......2300 - 2000 = 300 g

1 corn.....300 : 3 = 100 g


1 corn........1 pâine.......100 + 400 = 500 g
