Question 23421
What did you want to do, find a common denominator and subtract the fractions?

{{{((5c)/(8m))-((7m)/c)}}}


The LCD = 8mc


Multiply the first fraction by {{{c/c}}} and the second fraction by {{{ (8m)/(8m)) }}}.

{{{((5c)/(8m))*(c/c)-((7m)/c)*((8m)/(8m)) }}}

{{{(5c^2-56m^2)/( 8mc) }}}
