\(\frac{45.47-33}{45.46+12}\)
= \(\frac{45.\left(46+1\right)-33}{45.46+12}\)
= \(\frac{45.46+45-33}{45.46+12}\)
= \(\frac{45-33}{12}\)
= \(1\)
=> biểu thức trên = 1
\(\frac{2013.2014+2000}{2014.2014-15}\)
\(=\frac{2013.2014+2000}{2014.\left(2013+1\right)-15}\)
\(=\frac{2013.2014+2000}{2014.2013+2014-15}\)
\(=\frac{2000}{2014-15}\)
\(=\frac{2000}{1999}\)
=> biểu thức trên < 1
