Explicație pas cu pas:
6 / 11 = 18 / 33 → fractii echivalente, deoarece 6 × 33 = 11 × 18 = 198
→ produsul mezilor = produsul extremilor
sau 18 / 33 = ( 6 × 3 ) / ( 11 × 3 )
_________________________________________________
105 / 23 = 315 / 69 → fractii echivalente
( 105 × 3 ) / ( 23 × 3 ) = 315 / 69
→ amplific fractia cu 3
______________________________
41 / 72 = 164 / 288 → fractii echivalente
→ amplific fractia 41 / 72 cu 4; deoarece atat numaratorul, cat si numitorul sunt multiplii de 4 al lui 41 si 72
( 41 × 4 ) / ( 72 × 4 ) = 164 / 288
________________________________________
19 / 207 = 152 / 1656 → fractii echivalente
( 19 × 8 ) / ( 207 × 8 ) = 152 / 1 656
