Hok tốt!

Answer 2

\(a,\frac{45}{46}\)và \(\frac{2011}{2012}\)

Ta có: \(1-\frac{45}{46}=\frac{1}{46};1-\frac{2011}{2012}=\frac{1}{2012}\)

\(\frac{1}{46}>\frac{1}{2012}\Rightarrow\frac{45}{46}>\frac{2011}{2012}\)

\(b,\frac{2010}{2011}\)và \(\frac{17}{16}\)

Ta có: \(\frac{2010}{2011}< 1;\frac{17}{16}>1\Rightarrow\frac{2010}{2011}< \frac{17}{16}\)

Answer 3

a, 45/46 > 2011/2012

b, 2010 < 17/16
