B)3/2, 3/7,3/5,3/10.
C) 1/999,1111/999,11111/999,11/999.
D)1000/7,1000/11,1000/5, 1000/13​

Răspuns :

2/5 < 3/5 < 4/5 < 7/5

cmmmc(2, 5, 7, 10) = 70

³⁵⁾3/2 = 105/70

¹⁰⁾3/7 = 30/70

¹⁴⁾3/5 = 42/70

⁷⁾3/10 = 21/70

21/70 < 30/70 < 42/70 , 105/70

3/10 < 3/7 < 3/5 < 3/2

1/999 < 11/999 < 1111/999 < 11111/999

1000/13 < 1000/11 < 1000/7 < 1000/5
