a)
g.a+.g.b= x .globulete
g.a=250
g.b=180
g.a=g.b+1400
----------------------------
Cite globuri sunt in fiecare cutie
g.a-g.b=1400 globuri
250-180=70 cutii cuprind cele 1400 de globuri
1400:70=20 globulete sunt in fiecare cutie
g.a=250*20
g.a=5000 globulete (in 250 cutii)
g.b=180*20
g.b=3600 globulete (in 180 cutii)
a - b=1400 g
5000-3600=1400g
g.a+g.b=x g
5000+3600=8600 total globulete in 430 de cutii (250+180)
R=>20 globuri sunt intr-o cutie
b)
c.m+c.d=400caiete
c.m=35 teancuri
c.d=15 teancuri
-------------------------
Cate caiete sunt in fiecare teanc?
35+15=50 teancuri caiete
400:50=8 caiete in fiecare teanc
c.m=35*8
c.m=280 caiete matematica ( in 35 teancuri)
c.d=15*8
c.d=120 caiete dictando (in 15 teancuri)
280+120=400 caiete in total
R=> 8 caiete sunt intr-un teanc
