You can put this solution on YOUR website!
So then 63 items equals 84%.
\n" ); document.write( "Set up a ratio.
\n" ); document.write( "63 is to 84 as X is to 100.
\n" ); document.write( "\"63%2F84=X%2F100\"
\n" ); document.write( "\"X=6300%2F84\"
\n" ); document.write( "\"X=75\"
\n" ); document.write( "
\n" );
