Question

Afla numerele necunoscute. 8÷a1rest 3. b÷4=18rest3. c÷8=1rest2

Answer 1

Răspuns:

Explicație pas cu pas:

8 : a = 1 rest 3

a = ( 8 - 3) : 1

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

Answer 2

Răspuns:

8:a=1 rest 3

a=(8-3):1

a=5:1

a=5

v: 8:5=1 rest 3

b:4=18 rest 3

b=18×4+3

b=72+3

b=75

v: 75:4=18 rest 3

c:8=1rest 2

c=1×8+2

c=8+2

c=10
