Răspuns :

 raspunsul este 2 sacose
2kg+1000g+1000g+1kg+500g+500g+2kg+500g=8,5kg
=2kg+1kg+1kg+1kg+2kg+500g+500g+500g
=3kg+1kg+1kg+2kg+500g+500g+500g
=4kg+1kg+2kg+500g+500g+500g
=5kg+2kg+500g+500g+500g
=7kg+(500g+500g+500g)
=7kg+(1000g+500g)
=7kg+1500g                                              1500g=1,5kg
=7kg+1,5kg
=8,5kg
Totalul se imparte la 5kg
8,5kg÷5kg=1,7
Nu pot fi 1,7 pungi, deci sunt 2 pungi.
