c)\(\frac{2006}{2008}x\frac{2001}{2004}x\frac{2008}{2002}x\frac{2004}{2006}x\frac{1001}{2001}\)

Answer 1

. là x á nha

=\(\frac{2006}{2008}.\frac{2001}{2004}.\frac{2008}{2002}.\frac{2004}{2006}.\frac{1001}{2001}\)

=\(\frac{2006.2001.2008.2004.1001}{2008.2004.2002.2006.2001}\)

=\(\frac{1001}{2002}\)

Answer 2

= \(\frac{2006\cdot2001\cdot2008\cdot2004\cdot1001}{2008\cdot2004\cdot2002\cdot2006\cdot2001}\)

= \(\frac{1\cdot1\cdot1\cdot1\cdot1001}{1\cdot1\cdot2002\cdot1\cdot1}\)

= \(\frac{1}{2}\)

Answer 3

\(\frac{2006}{2008}.\frac{2001}{2004}.\frac{2008}{2002}.\frac{2004}{2006}\frac{1001}{2001}\)

\(=\frac{2006.2001.2008.2004.1001}{2008.2004.2002.2006.2001}\)

\(=\frac{1001}{2002}\)

\(=\frac{1}{2}\)
