Answer 2

Pentru a compara fractiile, le aducem la acelasi numitor .

cmmmc al numitorilor ( 4, 5, 6 ) = 4 × 3 × 5 = 60

3 / 4 = 45 / 60 → am amplificat fractia 3 / 4 cu 15

m / 5 = 12 m / 60

5 / 6 = 50 / 60

45 / 60 < 12 m / 60 < 50 / 60

45 < 12 m < 50 ⇒ 3 < m = 4 < 5

Verific: 45 < 48 < 50

Raspuns: m = 4
