Question

[Nguyen tuan cuong]

so sánh:

b,\(\frac{21}{22}và\frac{2011}{2012}\)

c,\(\frac{31}{95}và\frac{2012}{6035}\)

Answer 1

[I don't need you]

a) ta có: \(1-\frac{21}{22}=\frac{1}{22};1-\frac{2011}{2012}=\frac{1}{2012}\)

\(\Rightarrow\frac{1}{22}>\frac{1}{2012}\)

\(\Rightarrow1-\frac{21}{22}>1-\frac{2011}{2012}\Rightarrow\frac{21}{22}< \frac{2011}{2012}\)

b) ta có: \(\frac{31}{95}=0,32;\frac{2012}{6035}=0,33\)

=> 0,32 < 0,33

=> 31.95 < 2012/6035

Answer 2
