Question

Va rog sa ma ajutati la problemele 10,11,12.Dar trebuie rezolvate in metoda grafica!

Answer 1

10.
x+x+x:2+x:4=110 mere
x=4segmente
x=4segmente
x:2=2segmente
x:4=1segment
110:11=10(x:4)
4×10=40(x)
11.
a+b=111
a=b:2
a,b=?
a=2segmente
b=1segment
111:3=37(b)
37×2=74(a)
12.
S1+S2=117kg
S1-26kg=3×(S2-47kg)
S2-47
S1,S2=?
S1=3segmente+26
S2=1segment+47
117-73kg=44(4 S2)
44:4=11(S2)
11+47=58(S2)
3×11+26=33+26=59(S1)
Sper ca te-am ajutat!
