ta có : \(\frac{1717}{1919}=\frac{1717\div101}{1919\div101}=\frac{17}{19}\)
\(\Rightarrow\frac{17}{19}=\frac{1717}{1919}\)
vậy...................
1717/1919=1717:101/1919/101=17/19 => 17/19 = 1717/1919
Ta có:
\(\frac{1717}{1919}=\frac{17.101}{19.101}=\frac{17}{19}\)
--> \(\frac{1717}{1919}=\frac{17}{19}\)
Vậy \(\frac{1717}{1919}=\frac{17}{19}\)
