Question

Không tính giá trị biểu thức hãy so sánh 

\(\frac{1717}{8585}\)và \(\frac{1313}{5151}\)

Answer 1

Có : 1717/8585 = 17.101/85.101 = 17/85 = 1/5

        1313/5151 = 13.101/51.101 = 13/51

Mà 13/51 > 13/65 = 1/5

=> 1717/8585 < 1313/5151

Tk mk nha

Answer 2

Có : 1717/8585 = 17.101/85.101 = 17/85 = 1/5

        1313/5151 = 13.101/51.101 = 13/51

Mà 13/51 > 13/65 = 1/5

=> 1717/8585 < 1313/5151

Answer 3

Có :

1717/8585 = 17.101/85.101 = 17/85 = 1/5      

  1313/5151 = 13.101/51.101 = 13/51

Mà 13/51 > 13/65 = 1/5

=> 1717/8585 < 1313/5151

Answer 4

1717/8585=17/85=1/5

1313/5151=13/51

13/51>13/65=1/5

1717/8585 < 1313/5151

Answer 5

lỜI GIẢI ;

vì \(\frac{1717}{8585}\)\(=\)\(\frac{17}{85}\)\(=\)\(\frac{1}{5}\)

và \(\frac{1313}{5151}\)\(=\)\(\frac{13}{51}\)

mà \(\frac{13}{51}\)\(>\)\(\frac{13}{65}\)\(=\)\(\frac{1}{5}\)

Suy ra ; \(\frac{1717}{8585}\)\(< \)\(\frac{1313}{5151}\)

Answer 6

ta có 1717/8585:101=17/85

1313/5151:101=13/51

mà 13/51>13/65=1/5

suy ra 1717/8585<1313/5151
