\n" ); document.write( "A fraction has a value of 3/4. If 4 is added to its numerator and 8 is subtracted to its denominator. The value of the resulting fraction is 1. What is the original fraction. Show linear equation.
\n" ); document.write( "

Let multiplicative factor be x
\n" );
document.write( "Then original fraction = 
\n" );
document.write( "Adding 4 to the numerator, and subtracting 8 from the denominator results in: 
\n" );
document.write( "4x - 8 = 3x + 4 ------- Cross-multiplying
\n" );
document.write( "4x - 3x = 4 + 8
\n" );
document.write( "x, or multiplicative factor = 12
\n" );
document.write( "Numerator: 3(12) or 36
\n" );
document.write( "Denominator: 4(12) or 48
\n" );
document.write( " \n" );
document.write( "

\n" );
