You can put this solution on YOUR website!
If just the 20 kg of 15% protein mixture is wanted, then 12 kg. of the oats and 8 kg. of the barley.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Ratio of oats to barley NEEDED, $\"3%2F2=15%2F10\"$
\n" ); document.write( "Ratio of oats to barley AVAILABLE, $\"3%2F5=6%2F10\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "To make as much of the mixture as possible,
\n" ); document.write( "30 kilograms of the oats (17% protein)
\n" ); document.write( "and
\n" ); document.write( " $\"30%2A%282%2F3%29=20%2Akilograms\"$ of the barley.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Barley left over, 30 kilograms \n" ); document.write( "

\n" );
