Question

Va rog!!!!!!!!!!!!!!!!!!!!!

Answer 1

2p + 3k =200
2p + 6k =260
scadem prima relatie din a doua
2p+6k-2p-3k=260-200
3k=60
k=20 g suc(dintr-un kiwi)
2p +3x20=200
2p=200-60
2p=140
p=70 g suc( dintr-o portocala)

Answer 2

Metoda comparatiei:

2 portocale.........6 kiwi.......260 g suc
2 portocale.........3 kiwi......200 g suc

scadem cele doua relatii :
3 kiwi = 60 g suc
1 kiwi = 60 : 3 = 20 g suc

3 kiwi = 20 × 3 = 60 g suc
1 portocala = (200 - 60) : 2 = 140:2 = 70 g suc
