\(A=\frac{101+100+99+98+..+3+2+1}{101-100+99-98+..+3-2+1}=\frac{101\times\frac{102}{2}}{1+1+..+1}=\frac{101\times102}{2\times51}=101\)
\(B=\frac{423134.846267-423133}{423133.846267+423134}=\frac{423134^2+423134.423133-423133}{423133^2+423133.423134+423134}=\frac{423134^2+423133^2}{423134^2+423133^2}=1\)
