cat face: 8:a=1 rest 3,b:4=18rest 3,c:8=1rest 2

8:a=1 rest 3 a=(8·1)-3=5

b:4=18 rest 3

b=(18·4)-3=72-3=69

c:8=1 rest 2

c=(8·1)-2=6

Răspuns

Explicație pas cu pas:

8 : a = 1 rest 3

a = ( 8 - 3 ) : 1  → aplic teorema impartirii cu rest

a = 5 : 1

a = 5 → impartitorul

Verific:   8 : 5 = 1 rest 3

________________________

b : 4 = 18 rest 3

b = 18 × 4 + 3

b = 72 + 3

b = 75 → deimpartitul

Verific:    75 : 4 = 18 rest 3

_______________________

c : 8 = 1 rest 2

c = 1 × 8 + 2

c = 8 + 2

c = 10 → deimpartitul

Verific:    10 : 8 = 1 rest 2
