Question

Un bachet care cantareste 2kg si 750 g contine 4 paini a cate 500 g fiecare, doua bahete cu ubt a cate 250 g fiecare si o bucata de cascaval. Cate grame de cascaval sunt in bachet ? Imi trebuie repede va rog .

Answer 1

4paini = 500g*4= 2000g
2pachete unt = 250g*2=500g
2000g+500g = 2500g cantaresc 4paini si 2pachete de unt

=> cascavalul cantareste: 2750g-2500g=250g

Answer 2

bachet=2k si 750g;
4·500g+2·250g=2000g+500g=2kg si 500g;
⇒au ramas 750g-500g=250g;
⇒bucata de cascaval=250g;
