Algebra.Com's Answer #90297 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! he denominator of a fraction is is 3 times the numerator. If 8 is added to the numerator and 6 is subtracted from the denominator then the value is 8/9. Find the original fraction. \n" ); document.write( ": \n" ); document.write( "Quite frankly, I am not sure what you are doing, but here is how I would do it \n" ); document.write( ": \n" ); document.write( "Let x = numerator: \n" ); document.write( "It says'\"the denominator of a fraction is is 3 times the numerator.\" therefore: \n" ); document.write( "3x = denominator \n" ); document.write( "Our fraction: \n" ); document.write( " \n" ); document.write( "Then it says, \n" ); document.write( "\" If 8 is added to the numerator and 6 is subtracted from the denominator then the value is 8/9.\" so we can write: \n" ); document.write( " \n" ); document.write( "Cross multiply and we have: \n" ); document.write( ": \n" ); document.write( "8(3x-6) = 9(x+8) \n" ); document.write( ": \n" ); document.write( "Do some basic algebra here: \n" ); document.write( "24x - 48 = 9x + 72 \n" ); document.write( ": \n" ); document.write( "24x - 9x = 72 + 48 \n" ); document.write( ": \n" ); document.write( "15x = 120 \n" ); document.write( "x = \n" ); document.write( "x = 8 \n" ); document.write( ": \n" ); document.write( "Our original fraction: \n" ); document.write( ": \n" ); document.write( ": \n" ); document.write( "Check solution in the statement \n" ); document.write( " \"If 8 is added to the numerator and 6 is subtracted from the denominator then the value is 8/9.\" \n" ); document.write( ": \n" ); document.write( " \n" ); document.write( ": \n" ); document.write( ": \n" ); document.write( "How about this?
