If you had to do the problem 1/2 - 1/3 you would need to find a common denominator. The easiest way is to do 2 x 3 = 6. This approach doesn't guarantee the Lowest common denominator but it always gives a common denominator.\r

\n" ); document.write( "\"2%2F%285w%2B10%29+-+3%2F%282w-4%29\"
\n" ); document.write( "Factorise the bottom numbers as much as possible.
\n" ); document.write( "\"2%2F%285%28w%2B2%29%29+-+3%2F%282%28w-2%29%29\"
\n" ); document.write( "A common denominator is found by multiplying 5 x (w+2) x 2 x (w-2)
