You just stated that the original fraction is 2/3 and you ask what is this fraction. It's the same: 2/3. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Did you mean that the ratio of two variables is 2/3, and then according to the description, find those two numbers? That would be worded a little differently.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Let numerator be n
\n" ); document.write( "Let denominator be d.
\n" ); document.write( "\"n%2Fd+=+2%2F3\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The longer part of the description gives \"%28n%2B14%29%2F%28d-9%29=d%2Fn\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Working with the longer equation,\"+n%28n%2B14%29=d%28d-9%29\"
\n" ); document.write( "\"n%5E2%2B14n=d%5E2-9d\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Using the 2/3 equation, \"n=2d%2F3\", so try substituting:
\n" ); document.write( "\"d%5E2-9d=4d%5E2%2F9%2B14%2A2d%2F3\"
\n" ); document.write( "Multiply both sides by 9
\n" ); document.write( "\"9d%5E2-81d=4d%5E2%2B84d\"
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "\"5d%5E2-165d=0\"
\n" ); document.write( "\"d%5E2-33d=0\"
\n" ); document.write( "\"d%28d-33%29=0\"
\n" ); document.write( "... \"highlight%28d=33%29\"
\n" ); document.write( "meaning \"highlight%28n=22%29\".
\n" ); document.write( "
\n" ); document.write( "
\n" );
