Question

so sánh 2 PS \(\frac{2013}{2014}\)và \(\frac{2003}{2004}\)

Answer 1

2013/2014=1-1/2014

2003/2004=1-1/2004

vì 1/2014<1/2004

=) 1-1/2014>1-1/2004

hay 2013/2014>2003/2004

Answer 2

2013/2014>2003/2004 vì (1-2013/2014)<(1-2003/2004)

Answer 3

2013/2014>2003/2004

Answer 4

2013/2014>2003/2004

Answer 5

ta có :

    2013/2014 = 2014 / 2014 - 2013 / 2014 = 1 / 2014

     2003 / 2004 = 2004 / 2004 - 2003 / 2004 = 1 / 2004

  ta thấy : 1/ 2014 < 1 / 2004.Vậy 2013 / 2014 > 2003 / 2004

Answer 6

Ta so sánh phần bù:

\(\frac{2013}{2014}=1-\frac{2013}{2014}=\frac{1}{2014}\)                       Nên=>\(\frac{2013}{2014}>\frac{2003}{2004}\)

\(\frac{2003}{2004}=1-\frac{2003}{2004}=\frac{1}{2004}\)

Mà : \(\frac{1}{2014}< \frac{1}{2004}\)
