Question

Va rog ajutati-ma!!!!! Determinati toate nr care impartite la 11 dau restul egal cu catul

Answer 1

x:11 = c rest c
x= 11c + c
x= 12c   <=>x=M₈  =>x={12,24,36,48,60,72}

1) x=11 =>  12:11=1 rest 1

2) x=24  => 24:11=2 rest 2

3) x=36  => 36:11=3 rest 3

4) x=48 => 48:11=4 rest 4

5) x=60 => 60:11= 5 rest 5

6) x=72 => 72:11=6 rest 6

Answer 2

11x1+1= 12       12:11=1catul,1 restul
11x2+2=24         24:11=2rest 2
11x3+3=36         36:11=3rest 3    
11x4+4=48         48:11=4 rest 4
11x5+5=60          60:11= 5 rest 5
11x6+6=72          72: 11=6 rest 6
11x7+7=84           84:11=  7 rest 7
11x8+8=96           96:11=8 rest 8
11x9+9=108        108:11=9 rest 9
