16 / 23 = 32 / 46 = 80 / 115 = 64 / 92 = 176 / 253
________________________
16 × 2 = 32 / 23 × 2 = 46
_________________________
115 : 23 = 5 → fractia 16 / 23 se amplifica cu 5 ⇒ 16 × 5 = 80
______________________________________________
92 : 23 = 4 ⇔ fractia 16 / 23 se amplifica cu 4 ⇒ 16 × 4 = 64
_________________________________________________
253 : 23 = 11 ⇔ fractia 16 / 23 se amplifica cu 11 ⇒ 16 x 11 = 176
