A student places 2.5 grams of salt in \r\n" );
document.write( "90 ml. of water. She then transfers 30 ml. \r\n" );
document.write( "of that solution to an evaporating dish. \r\n" );
document.write( "How many grams of salt are in the 30 ml. \r\n" );
document.write( "of solution?\r\n" );
document.write( "\r\n" );
document.write( "Use the proportion:\r\n" );
document.write( "\r\n" );
document.write( "2.5 g of salt IS TO 90 ml of liquid AS \r\n" );
document.write( "      x g of salt IS TO 30 ml of liquid\r\n" );
document.write( "\r\n" );
document.write( "Replace the \"IS TO\"'s by \" / \"'s and the \r\n" );
document.write( "\"AS\" by \" = \"\r\n" );
document.write( "\r\n" );
document.write( "  2.5/90 = x/30\r\n" );
document.write( "\r\n" );
document.write( "Solve that and get .833333 grams of salt\r\n" );
document.write( "(or 5/6 grams if you use fraction 2 1/2,\r\n" );
document.write( "which is 5/2 instead of decimal 2.5)\r\n" );
