Simplific cu 5 !
5/10 = 1/2 ;
25/15 = 5/3 ;
115/85=23 /17 ;
5n/55 = n /11 ;
20n/(10n+5)=20n / 5(2n+1) = 4n/(2n+1) ;
5/10 = 1/2 ;
25/15 = 5/3 ;
115/85=23 /17 ;
5n/55 = n /11 ;
20n/(10n+5)=20n / 5(2n+1) = 4n/(2n+1) ;
5/10 = 1/2 ( prin 5)
25/15= 5/3 ( prin 5)
115/85= 23/17 ( prin 5)
5n/55= n/11 ( prin 5)
25/15= 5/3 ( prin 5)
115/85= 23/17 ( prin 5)
5n/55= n/11 ( prin 5)
