Question

Aflati toate fractiile de forma ab unde a apartine la D12 si b apartine la D35

Answer 1

a∈D12⇒D12=[1,2,3,4,6,12];
⇒a∈[1,2,3,4,6,12];
b∈D35⇒D35∈[1,5,7,35];
⇒b∈[1,5,7,35];
⇒a/b⇒a-numarator⇒b-numitor;
⇒a/b∈[1/1,1/5,1/7,1/35,2/1,2/5,2/7,2/35,3/1,3/5,3/7,3/35,4/1,4/5,4/7,4/35,6/1,6/5,6/7,6/35,12/1,12/5,12/7,12/35]⇒6·4=24[fractii de forma a/b];
