\n" ); document.write( "How do I show my son how to solve this math problem:\r
\n" ); document.write( "\n" ); document.write( "4/5 times ___ = 2/5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Two examples:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2 * a = 6. Therefore, a = \"6%2F2\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "3 * b = 15. Therefore, b = \"15%2F3\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Do you get it now?\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"4%2F5\" times _S_ = \"2%2F5\". Therefore, S = \"2%2F5\" ÷ \"4%2F5\" ----- \"S+=+%282%2F5%29+%2A+%285%2F4%29\" ------ \"S+=+%28cross%282%29%2Fcross%285%29%29+%2A+%28cross%285%29%2Fcross%284%292%29\" ------ \"highlight_green%281%2F2%29\"
