a) 1995/1996 và 1996/1997
Ta có: 1995/1996=1 - 1/1996
1996/1997=1 - 1/1997
Vì 1/1996 > 1/1997 nên 1995/1996 < 1996/1997
b) Ta có: \(\frac{2121}{3737}=\frac{2121:101}{3737:101}=\frac{21}{37}\); \(\frac{212121}{373737}=\frac{212121:10101}{373737:10101}=\frac{21}{37}\)
Vì 21/37=21/37 nên 2121/3737 = 212121/373737
a, Ta có: 1-1995/1996=1/1996 ; 1-1996/1997=1/1997
do 1/1996 > 1/1997 nên 1995/1996 < 1996 1997
ai thấy đúng thì k cho mình nha
