We can write this same ratio as
\n" ); document.write( "5x:2x:7x
\n" ); document.write( "Thus the difference between the largest and the smallest is
\n" ); document.write( "7x - 2x = 54
\n" ); document.write( "5x = 54
\n" ); document.write( "x = 10.8
\n" ); document.write( "Thus the numbers must be
\n" ); document.write( "54 : 21.6 : 75.6
\n" ); document.write( "Add them up to get
\n" ); document.write( "151.2
\n" ); document.write( "
\n" );
