Question

10 iepuri consuma in 10 zile o cantitate de 200 kg de morcovi. ce cantitate vor consuma opt iepuri in 25 de zile?

Answer 1

10=200 kg
20=200x2=400 kg
25= 400+(200:2)=400+100=500 kg

Answer 2

considerand ca iepurii mananca in mod egal, intr-o singura zi 10 iepuri vor consuma 200 kg : 10 zile = 20 kg / zi 

un singur iepure va manca 20 kg/zi : 10 = 2 kg / zi  = ratia unui iepure 

in 25 de zile, 8 iepuri vor manca  ratia unui iepure x 25 zile x 8 iepuri : 
 2kg/zi x 25 zile x 8 = 400 kg  morcovi
