Question

ex 4 si 5 daca puteți

Answer 1

4 ) impartind un nr la 6 putem obtine resturile : 0; 1; 2; 3; 4; 5
=> 0+1+2+3+4+5= 15
5) x:7=5+ restul
Impartind un nr la 7 putem avea resturile : 0;1;2;3;4;5;6
=> x = 7×5 + resrul = 35 + restul
Restul= R
R= 0 => x= 35
R= 1 => x= 36
R = 2 => x = 37
R = 3 => x = 38
R = 4 => x= 39
R = 5 => x= 40
R = 6 => x = 41
