Сравни дроби:

а) \(\cfrac{5}{12}\lt \cfrac{3}{4}\) , так как \(\cfrac{^{3/}3}{4}=\cfrac{9}{12}\) и \(\cfrac{5}{12}\lt \cfrac{9}{12}\) ;

б) \(\cfrac{4}{15}\) [ \(\lt\) | \(\gt\) | \(=\) ] \(\cfrac{1}{3}\) , так как \(\cfrac{1}{3}=\) [ ] и \(\cfrac{4}{15}\) [ \(\lt\) | \(\gt\) | \(=\) ][ ];

в) \(\cfrac{5}{7}\) [ \(\lt\) | \(\gt\) | \(=\) ] \(\cfrac{24}{35}\) , так как \(\cfrac{5}{7}=\) [ ] и [ ][ \(\lt\) | \(\gt\) | \(=\) ] \(\cfrac{24}{35}\) ;

г) \(\cfrac{2}{7}\) [ \(\lt\) | \(\gt\) | \(=\) ] \(\cfrac{9}{28}\) , так как \(\cfrac{2}{7} =\) [ ] и [ ][ \(\lt\) | \(\gt\) | \(=\) ] \(\cfrac{9}{28}\) ;

д) \(\cfrac{5}{32}\) [ \(\lt\) | \(\gt\) | \(=\) ] \(\cfrac{9}{64}\) , так как \(\cfrac{5}{32}=\) [ ] и [ ][ \(\lt\) | \(\gt\) | \(=\) ] \(\cfrac{9}{64}\) .
