$\"4t%2F9w%5E2\"$ , $\"5%2F6wt\"$
\n" ); document.write( "This is all about picking your selective 1s 1/1=1 5/5=1 4x/4x=1
\n" ); document.write( "to get the common denom its easiest to just multiply the to denom values together and in doing so it will change the look of the numerator. it looks confusing but for example: $\"%281%2F1%29%285x%2F5y%29=%285x%2F5y%29\"$ $\"%281z%2F1z%29%285x%2F5y%29=%285xz%2F5yz%29\"$
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "back to the problem:
\n" ); document.write( " $\"%286wt%2F6wt%29=1%2F1\"$ $\"%289w%5E2%2F9w%5E2%29=1%2F1\"$
\n" ); document.write( " $\"%284t%2F9w%5E2%29%2A%286wt%2F6wt%29\"$ , $\"%285%2F6wt%29%2A%289w%5E2%2F9w%5E2%29\"$
\n" ); document.write( " $\"%284t%2A6wt%29%2F%289w%5E2%2A6wt%29\"$ , $\"%285%2A9w%5E2%29%2F%286wt%2A9w%5E2%29\"$
\n" ); document.write( " $\"highlight%28%2824wt%5E2%29%2F%2854w%5E3t%29%29\"$ , $\"highlight%28%2845w%5E2%29%2F%2854w%5E3t%29%29\"$ \n" ); document.write( "
