解：499又2004分之1999 除以5
= 499又1999/2004 × 1/5
=【（499 + 1-2004/2004）+ 1999/2004】× 1/5
=【500 - 2004/2004 + 1999/2004】× 1/5
=【500 - 5/2004】× 1/5

499又2004分之1999 除以5
=499又1999/2004×1/5
=[（499+1-2004/2004）+1999/2004]×1/5
=[500-2004/2004+1999/2004]×1/5
=[500-5/2004]×1/5
=500×1/5-5/2004×1/5
=100-1/2004
=99又2003/2004

原式=(499十1-5/2004)除以5
=(500-5/2004)除以5
=500/5-5/2004除以5
=100-1/2004
=99又2004分之2003

499又2004分之1999 ÷5
=（500-5/2004)÷5
=100-1/2004
=99又2004分之2003
