\(\frac{16}{48}=\frac{16:16}{48:16}=\frac{1}{3}\);\(\frac{14}{35}=\frac{14:7}{35:7}=\frac{2}{5}\)
\(\frac{1}{3}=\frac{1\cdot5}{3\cdot5}=\frac{5}{15}\); \(\frac{2}{5}=\frac{2\cdot3}{5\cdot3}=\frac{6}{15}\)

2279/3127 = 43/59
3337/4473 = 47/63
43/59 = 2709/3717
47/63 = 2962/3717
suy ra 2962/3717 > 2709/3717
3337/4473 > 2279/3127
k mik nha ^^
\(\frac{2279}{3127}\)= \(\frac{43}{59}\)
\(\frac{3337}{4473}\)= \(\frac{43}{59}\) mà \(\frac{43}{59}\)= \(\frac{43}{59}\) =>\(\frac{2279}{3127}\)= \(\frac{3337}{4473}\)

Cách 1 :
Rút gọn : 12/16 = 3/4 , 28/21 = 4/3
So sánh : 12/16 < 28/21
Cách 2 :
So sánh Vì 12/16 < 1 và 28/ 21 > 1 nên 28/21 > 12/16

34 / 51 = 34 : 17 / 51 : 17
= 2/3
Vậy 34/51 = 2/3
Chúc bạn học tốt!
