let the total weight of a packet be \"m\"\r
\n" ); document.write( "\n" ); document.write( "if the total weight of a packet is \"%281%2F2%29kg\" more than \"%284%2F5%29\" of its weight, we have:\r
\n" ); document.write( "\n" ); document.write( "\"m=%284%2F5%29m%2B%281%2F2%29kg\"\r
\n" ); document.write( "\n" ); document.write( "\"m=2%284%2F%282%2A5%29%29m%2B5%281%2F%285%2A2%29%29kg\"\r
\n" ); document.write( "\n" ); document.write( "\"m=%288%2F10%29m%2B%285%2F10%29kg\".....both sides multiply by \"10\"\r
\n" ); document.write( "\n" ); document.write( "\"10m=8m%2B5kg\"\r
\n" ); document.write( "\n" ); document.write( "\"10m-8m=5kg\"\r
\n" ); document.write( "\n" ); document.write( "\"2m=5kg\"\r
\n" ); document.write( "\n" ); document.write( "\"m=5kg%2F2\"\r
\n" ); document.write( "\n" ); document.write( "\"m=2.5kg\"->the total weight of a packet\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "check:\r
\n" ); document.write( "\n" ); document.write( "\"%284%2F5%29\" of it will be:\r
\n" ); document.write( "\n" ); document.write( "\"%284%2F5%292.5kg=10kg%2F5=2kg\" -> which is \"%281%2F2%29kg\" less than \"m=2.5kg\"
\n" ); document.write( "
