If y varies inversely as x...
\n" ); document.write( "
Then \"y\"\"%22%22=%22%22\"\"k%2Fx\"
and x is increased in the ratio 3:5
\r\n" );
document.write( "\r\n" );
document.write( "Then 
how is y changed?
Cross-multiply:\r\n" );
document.write( "\r\n" );
document.write( "\"5%28matrix%281%2C2%2COLD%2Cx%29%29\"\"%22%22=%22%22\"\"3%28matrix%281%2C2%2CNew%2Cx%29%29\"\r\n" );
document.write( "\r\n" );
document.write( "\"expr%285%2F3%29%28matrix%281%2C2%2COLD%2Cx%29%29\"\"%22%22=%22%22\"\"matrix%281%2C2%2CNew%2Cx%29\"\r\n" );
document.write( "\r\n" );
document.write( "Replace x by \"expr%285%2F3%29x\" in\r\n" );

document.write( "\"y\"\"%22%22=%22%22\"\"k%2Fx\"\r\n" );

document.write( "\r\n" );
document.write( "So y is decreased in the ratio 5:3.\r\n" );
