A computer virus is eating disk space. During the first day it eats 1/2 of the disk.During the second day, it eats 1/3 of the remaining disk space. The third day it eats 1/4 of what still remains and the fourth day it eats 1/5 of what is left. What fraction of the original disk space remains intact?
\n" ); document.write( "


\n" ); document.write( "another hectic fraction problem try to stay with me
\n" ); document.write( "D= original disk space
\n" ); document.write( "1st \"%281%2F2%29D\" which leaves \"%281%2F2%29D\" remaining
\n" ); document.write( "2nd \"%281%2F3%29%28%281%2F2%29D%29=%281%2F6%29D\" so then \"%281%2F2%29D-%281%2F6%29D=%281%2F3%29D\" remaining
\n" ); document.write( "3rd \"%281%2F4%29%28%281%2F3%29D%29=%281%2F12%29D\" so then \"%281%2F3%29D-%281%2F12%29D=%281%2F4%29D\" remaining
\n" ); document.write( "4th \"%281%2F5%29%28%281%2F4%29D%29=%281%2F20%29D\" so then \"%281%2F4%29D-%281%2F20%29D=%281%2F5%29D\" remaining
\n" ); document.write( "so \"1%2F5\"of the original disk space is left \n" ); document.write( "

\n" );
