Question

Aflati toate numerele naturale care impartite la 15 dau catul 11

Answer 1

d:s=c si rest
d=cxi+r   i>r
d=11x15 +r  15>r  ⇒r poate lua valori de la 0 la 14
r=14⇒d=11x15+14=179⇒179
r=13⇒d=11x15+13=178⇒178
.
.
.r=0⇒d=11x15+0=165⇒165

Rapuns _165,166,167,168,169,170,171,172,,173,174,175,176,177,178,179 sunt numerele cautate

Answer 2

r=14⇒d=11x15+14=179⇒179
r=13⇒d=11x15+13=178⇒178.r=0⇒d=11x15+0=165⇒165

Rezulta ca : 165,166,167,168,169,170,171,172,,173,174,175,176,177,178,179 sunt numerele cerute.
