let x = the amount he earns in all months except july and august.
\n" ); document.write( "in july he earns 5x.
\n" ); document.write( "in august he earns 3x.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the total he earns all year is 10x + 3x + 5x = 18x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "in july and august he earns 3x + 5x = 8x.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the fraction of his entire years earning that he earns in july and august is 8x/18x = 4/9.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "4/9 * 18 = 8
\n" ); document.write( "5/9 * 18 = 10\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "add them up and you get a total of 18.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the fraction you are looking for is 4/9.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "that's the fraction of his total earnings that he earns in july and august.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
