Question

Cate sticle de jumatate de litru se pot umple cu 8 pahare de 250ml?

Answer 1

250 x 4 = 1000 ml ( adica 1 litru )
250 x 8 = 2000 ml ( adica 2 litri)
jumatate de litru = 500 ml ( adica 2 pahare de 250 ml)
4 x 500 ml = 2000 ml 
Deci se pot umple 4 sticle de jumatate de litru cu 8 pahare de 250 ml.

Answer 2

o sticla de jumatate de litru are 500 ml = 2 pahare 

8  : 2 = 4 sticle de jumatate de litru 

Sau 8 pahare de 250 ml contin: 8 × 250 ml = 2 000  ml 

2 000 ml : 500 l = 4 sticle de 500 ml( sau jumatate de litru)
