Question

Impartind un numar natural n la 85 obtinem restul 81.Ce rest vom obtine daca impartim numarul n la 17?

Answer 1

restul este 13
85-81=4
17-4=13

Answer 2

varianta 1)

n:85=c*85+81
n:17=c*17+r
r=?
85-81=4
17-4=13 
r=13

Varianta 2)

n:85=c+81
n=(85*81)+81
n=6885 +81
n=6966

6966:85=81 rest 81
6966=(85*81)+81
6966=6885+81
6966=6966

6966:17=409 rest 13
6966=(409*17)+13
6966=6953+13
6966=6966

r=13
