Answer 1

Răspuns:

..3 cornuri.......5 pâini.......2300g

4 cornuri.........2 pâini.......1200 G

1 corn +1 pâine.....= ? g

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

0 cornuri......14 pâini.....5600 g

20-6=14 pâini

9200-3600=5600 g (au 14 pâini)

5600 ÷14=400 g o pâine

2×400=800 g (2 pâini)

1200-800=400 g (4 cornuri)

400÷ 4= 100 g (un corn)
