(1)  {{{0}}}{{{""<""}}}{{{a}}}{{{""<""}}}{{{b}}}

Multiply (1) through by a

{{{0}}}{{{""<""}}}{{{a^2}}}{{{""<""}}}{{{ab}}}

Multiply (1) through by b

{{{0}}}{{{""<""}}}{{{ab}}}{{{""<""}}}{{{b^2}}}

{{{a^2}}}{{{""<""}}}{{{ab}}}{{{""<""}}}{{{b^2}}}

Add ab to all three sides

{{{a^2+ab}}}{{{""<""}}}{{{2ab}}}{{{""<""}}}{{{ab+b^2}}}

{{{a(a+b)}}}{{{""<""}}}{{{2ab}}}{{{""<""}}}{{{b(a+b)}}}

Divide all three sides by a+b

{{{a}}}{{{""<""}}}{{{(2ab)/(a+b)}}}{{{""<""}}}{{{b}}}

{{{a}}}{{{""<""}}}{{{1^""/((a+b)/(2ab))}}}{{{""<""}}}{{{b}}}

{{{a}}}{{{""<""}}}{{{1^""/(1/(2b)+1/(2a))}}}{{{""<""}}}{{{b}}}

{{{a}}}{{{""<""}}}{{{1^""/(expr(1/2)(1/b+1/a))}}}{{{""<""}}}{{{b}}}

{{{a}}}{{{""<""}}}{{{1^""/(1/h)}}}{{{""<""}}}{{{b}}}

{{{a}}}{{{""<""}}}{{{h}}}{{{""<""}}}{{{b}}}
