Сравни дроби

а) \(\cfrac{3}{5}\) и \(\cfrac{5}{12}\) :

\(\cfrac{3}{5}=\cfrac{36}{60}\) , \(\, \cfrac{5}{12}=\cfrac{25}{60}\) ,

\(\, \cfrac{3}{5}\gt\cfrac{5}{12}\) ;

б) \(\cfrac{1}{2}\) и \(\cfrac{7}{18}\) :

\(\cfrac{1}{2}=\) [ ], \(\, \cfrac{7}{18}=\) [ ],

\(\cfrac{1}{2}\) [ \(\gt\) | \(\lt\) | \(=\) ] \(\cfrac{7}{18}\) ;

в) \(\cfrac{5}{7}\) и \(\cfrac{5}{6}\) :

\(\cfrac{5}{7}=\) [ ], \(\cfrac{5}{6}=\) [ ],

\(\cfrac{5}{7}\) [ \(\gt\) | \(\lt\) | \(=\) ] \(\cfrac{5}{6}\) ;

г) \(\cfrac{5}{8}\) и \(\cfrac{7}{12}\) :

\(\cfrac{5}{8}=\) [ ], \(\cfrac{7}{12}=\) [ ],

\( \cfrac{5}{8}\) [ \(\gt\) | \(\lt\) | \(=\) ] \(\cfrac{7}{12}\) ;

д) \(\cfrac{7}{9}\) и \(\cfrac{5}{6}\) :

\(\cfrac{7}{9}=\) [ ], \( \cfrac{5}{6}=\) [ ],

\(\cfrac{7}{9}\) [ \(\gt\) | \(\lt\) | \(=\) ] \(\cfrac{5}{6}\) ;

e) \(\cfrac{11}{18}\) и \(\cfrac{7}{12}\) :

\(\cfrac{11}{18}=\) [ ], \(\cfrac{7}{12}=\) [ ],

\( \cfrac{11}{18}\) [ \(\gt\) | \(\lt\) | \(=\) ] \(\cfrac{7}{12}\) .
