<PRE><B>Question 1140935</B>
what number is halfway between-5/39 and -6/117?
:
39 * 117 = 4563 is the common denominator
{{{585/4563}}} - {{{234/4563}}} = {{{351/4563}}} they have the same sign so we don&#39;t have to worry about that now
:
find half of {{{351/4563}}} 
{{{351/4563}}} * {{{1/2}}} = {{{351/9126}}}
add to {{{234/4563}}}
{{{234/4563}}} + {{{351/9126}}}
Common denominator is 9126
{{{464/9126}}} + {{{351/9126}}} = {{{-815/9126}}} is half-way
