You can put this solution on YOUR website!
Percentage = part/whole\r
\n" ); document.write( "\n" ); document.write( "Part:
\n" ); document.write( "You are adding 1 ounce, but only half of it is malathion. So the part is 0.5 oz.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Whole:
\n" ); document.write( "you have added 1 oz to 128 oz so the whole is 129 oz\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "percentage = 0.5 ounce/129 oz
\n" ); document.write( "pct = 3.9% (this is rounded)\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(Bottom line: don't use toxins like malathion.)
\n" ); document.write( "
\n" );
