You can put this solution on YOUR website!
Set up the ratio:
\n" ); document.write( " $\"7%2F%28Nitrogen%29+=+5%2F%28Phosphorus%29+=+3%2F%28Potash%29+\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You need to solve this equation:
\n" ); document.write( " $\"7%2F35+=+5%2F%28Phosphorus%29+=+3%2F%28Potash%29\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "However, the faster way to do this is to recognize that the first denominator is 5 times the numerator. Therefore, the other denominators will each be 5 times the respective numerators. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Therefore, there will be 5*5 = 25 kg phosphorus and 5 *3 = 15 kg potash. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "R^2 at SCC \n" ); document.write( "
