Question

Pentru o gradinita s-au cumparat 18 litri de suc. Din intreaga cantitate , 1 pe 3 este depozitata in sticle de 5 decilitri , iar restul in sticle de 250 ml. Cate sticle cu suc s-au cumparat??

Answer 1

1/3 ·18⇒18/3=6[litri-de suc];
⇒6l=60dl;
⇒60dl/5l⇒12[sticle];
⇒au ramas 18-6=12[litri-de suc];
⇒12l=12000ml;
⇒12000ml/250ml⇒48[sticle]
⇒s-au cumparat 12+48=60[sticle cu suc];

Answer 2

18:3=6litri
6 l=6000ml
1 dl=100ml
5 dl=500ml
6000:500=12 sticle 500ml/5dl

18l-6l=12litri
12litri=12000ml
12000:250ml=48 sticle
 R=12/5dl
     48/250 ml
12+48=60sticle
