Question

Mama a preparat 9 l de sirop de capsune si cu 2 l mai mult sirop de zmeura.Cate sticle umple mama,daca pune siropul: a) In sticle de un l? b) In sticle de jumatate de litru? c) Un sfert din cantitate in sticle de jumate de litru,iar restul in sticle de un litru?

Answer 1

9l s. capsune
9+2l s. zmeura=11l s. zmeura
a) sticle de 1l: (9l+11l):1l=20 sticle
b)20l:1\2l=40 sticle
c)(1\4)*20=5 => 5l in sticle de 1\2 litri => 10 sticle de 1/2 litri, 15l in sticle de 1 litru => 15 sticle. 15 sticle+10 sticle= 25 sticle.

Answer 2

9 litri sirop capsune
9+2=11 litri sirop zmeura
total sirop=9+11=20 litri sirop
a) In sticle de un l?
20 litri : 1litru=20 sticle de 1 litru

b) In sticle de jumatate de litru?
 20 litri:0,5 litri= 40 sticle de 0,5 litri

c) Un sfert din cantitate in sticle de jumatate de litru,iar restul in sticle de un litru? 1/4 din 20=5 litri          in sticle de 1/2 litri= 10 sticle de 1/2 litri

3/4 din 20=15 litri..................15 litri in sticle 1 litru=15 sticlede 1 litru
deci
Un sfert din cantitate in sticle de jumate de litru,iar restul in sticle de un litru? 
=10 sticle de 1/2 litri+15 sticle de 1 litru=25 sticle
