Question

a+ b= 33 ; daca impartim pe b la a obtinem catul 4 si restul 3. cu metoda grafica

Answer 1

a + b = 33
b : a = 4 rest 3
b = 4a + 3
a + 4a + 3 = 33
5a = 33 - 3
a = 30 : 5
a = 6
b = 33 - 6
b = 27
a   ___/
b   ___/___/___/___/  + 3
33 - 3 = 30
30 : 5 segmente = 6
a = 6
b = 27

Answer 2

/___/___/___/___/+3 nr b
/___/ nr a
Suma=33
Egalam suma segmentelor
33-3=30
4+1=5 segmente egale
30:5=6 un segment ( nr a)
6×4+3=24+3=27 nr b
Verificam: 27:6=4 rest 3
27+6=33
