Răspuns

Explicație pas cu pas:

3 / 5 = ( 3 x 3 ) / ( 5 x 3 ) = 9 / 15 →  am amplificat fractia initiala cu 3

_____________________________________________________

3 / 5 = ( 3 x 4 ) / ( 5 x 4 ) = 12 / 20 → amplificata cu 4

____________________________________________________

3 / 5 = ( 3 x 7 ) / ( 5 x 7 ) = 21 / 35 → amplificata cu 7
