Question 76516
How do I simplify this 1/x - 1/b over 1/xb + 1/2
:
{{{1/x - 1/b}}} 
---------- = 
{{{1/(xb) + 1/2}}}
:
Convert the fractions into a single fraction with a common denominator
{{{((b-x))/(xb)}}}
---------- =
{{{((2+(xb)))/(2xb)}}}
:
Remember when you divide fractions, you invert the dividing fraction and mult:
{{{((b-x))/(xb)}}}  *  {{{(2xb)/((2+xb))}}} = {{{((b-x))/1}}}  *  {{{(2)/((2+xb))}}} =  {{{(2(b-x))/((2 + xb))}}}; canceled the xb's
