Question

Determinati toate fractiile de forma xy/abc echivalente cu fractia 3/8

Answer 1

3/8      de forma xy/abc      
100:8=12 si rest 4 
8x13=104
3x13=39
  deci se inmulteste fractia cu 13,14,15.......33 si obtinem :
39/104
42/ 112    in acest caz a=b
45/ 120
48/ 128
51/ 136
54/ 144   in acest caz b=c
57/ 152
60/ 160
63/ 168
66/ 176    in acest caz x=y
69/ 184
72/ 192
75/ 200   in acest caz b=c
78/ 208
81/ 216
84/ 224  in acest caz a=b
87/232   in acest caz a=c
90/ 240
93/ 248
96/ 256
 99/ 264    in acest caz x=y
