We continue to adopt notations and methods used
in the papers illustrated by Yang (2009, 2010) to investigate the monotonicity properties of the ratio of
mixed two-parameter homogeneous means. As consequences of our results, the
monotonicity properties of four ratios of mixed Stolarsky means are presented,
which generalize certain known results, and some known and new inequalities
of ratios of means are established.
