Question

3 banane si 5 mineole cantaresc impreuna 810 g. Cat cantareste fiecare, daca o banana si o mineola cantaresc (impreuna) 220 g?

Answer 1

810-660=210
210:2=110 miniole
110 banane

Answer 2

3 b+5 m=810 l
1 b+1 m=220 l×3
3 b+5 m=810
3 b+3 m=660
5 m-3 m=810-660
2 m=150
m=150:2=75 g
1 b+75 g=220 g
1 b=220-75=145 g
