Answer 1

3cornuri......5paini......2300g/*4

4cornuri......2paini......1200g/*3

12cornuri......20paini......9200g

12cornuri......6paini.......3600g

1) 20-6=14 paini

2) 9200g-3600g=5600g

14paini......5600g

3) 5600g÷14=400g (1 paine)

4) 400*6=2400g (6 paini)

5) 3600-2400g=1200g (12 cornuri)

6) 1200g:12=100g (1 corn)

1corn+1paine=500g
