\n" ); document.write( "\n" ); document.write( " $\"3%2A2.5=x%2A1.5\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"7.5%2F1.5=x\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x=5\"$ \r
\n" ); document.write( "\n" ); document.write( "it takes $\"5\"$ bundles of grass to weave a similar mat of diameter $\"2.5m\"$ \n" ); document.write( "
