A, B, C, D, and E. are consecutive points on a line. If AB/BC=1/3, BC/CD=1/4,
\n" ); document.write( "and CD/DE=1/2, what is AC/BE ?
\n" ); document.write( "
\r\n" );
document.write( "\r\n" );
document.write( "Begin by letting AB = 1 unit.  Then you'll see how I got these numbers:\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "let AB = 1 unit, then\r\n" );
document.write( "\r\n" );
document.write( "\"%28AB%29%2F%28BC%29=1%2F3\"\r\n" );
document.write( "\"1%2F%28BC%29=1%2F3\"\r\n" );
document.write( "Cross-multiply,\r\n" );
document.write( "\"3=BC\"\r\n" );
document.write( "So BC = 3 units\r\n" );

document.write( "\"12=CD\"\r\n" );
document.write( "So CD = 12 units\r\n" );

document.write( "Cross-multiply,\r\n" );
document.write( "\"24=DE\"\r\n" );
document.write( "So DE = 24 units\r\n" );
document.write( "\r\n" );
document.write( "
what is AC/BE ?
