\n" ); document.write( "\n" ); document.write( "The ratio of Jonathan’s age to David’s age is 6:5. In seven years it will be 7:6. What are their ages now.\r

Let MULTIPLICATIVE factor of each person’s age be x
\n" );
document.write( "Then Jonathan’s age is: 6x and David’s is: 5x
\n" );
document.write( "We then get: 
\n" );
document.write( "6(6x + 7) = 7(5x + 7) ---------- Cross-multiplying 
\n" );
document.write( "36x + 42 = 35x + 49
\n" );
document.write( "36x – 35x = 49 – 42
\n" );
document.write( "x, or MULTIPLICATIVE factor of each person’s age is 7
\n" );
document.write( "
\n" );
document.write( "It is that simple!! \n" );
document.write( "

\n" );
