Question

Doi porci mananca intr o zi tot atatea graunte cat mananca 10 gaini .Cate kg de graunte mananca pe zi fiecare animal,daca un porc si o gaina consuma zilnic 6 kg de graunte ?

Answer 1

2p=10g
p=10:2
p=5kg./zi (1 porc)

5kg.*2=10g.
10gaini=10kg.
1g=10:10
g=1kg/zi (o gaina)

Answer 2

2p=10g
P+g=6
P=6-g
2(6-g)=10g
12-2g=10g
12g=12
G=12:12
G=1
P=6-1
P=5
Un porc mănâncă 5kg, iar o găina 1kg
