Сравни дроби и запиши доказательство строго по образцу:

а) \(\cfrac{-5}{4} \gt \cfrac{-4}{3}\) , так как \(\cfrac{^{3/}-5}{4}=\cfrac{-15}{12}\) , \(\cfrac{^{4/}-4}{3}=\cfrac{-16}{12}\) и \(\cfrac{-15}{12} \gt \cfrac{-16}{12}\) ;

б) \(\dfrac{3}{4}\) [ \(\gt\) | \(\lt\) | \(=\) ] \(\dfrac{4}{5}\) , так как \(\dfrac{3}{4}=\) [ ], \(\dfrac{4}{5}=\) [ ] и [ ][ \(\gt\) | \(\lt\) | \(=\) ][ ];

в) \(\dfrac{-3}{5}\) [ \(\gt\) | \(\lt\) | \(=\) ] \(\dfrac{-4}{7}\) , так как \(\dfrac{-3}{5}=\) [ ], \(\dfrac{-4}{7}=\) [ ] и [ ][ \(\gt\) | \(\lt\) | \(=\) ][ ];

г) \(\dfrac{-7}{6}\) [ \(\gt\) | \(\lt\) | \(=\) ] \(\dfrac{-8}{7}\) , так как \(\dfrac{-7}{6}=\) [ ], \(\dfrac{-8}{7}=\) [ ] и [ ][ \(\gt\) | \(\lt\) | \(=\) ][ ];

д) \(\dfrac{-7}{8}\) [ \(\gt\) | \(\lt\) | \(=\) ] \(\dfrac{-8}{9}\) , так как \(\dfrac{-7}{8}=\) [ ], \(\dfrac{-8}{9}=\) [ ] и [ ][ \(\gt\) | \(\lt\) | \(=\) ][ ].
