\(\frac{23}{57}\)> \(\frac{34}{11}\) nha
ta có:\(\frac{23}{7}=\frac{23.11}{7.11}=\frac{253}{77}\)
\(\frac{34}{11}=\frac{34.7}{11.7}=\frac{238}{77}\)
vì \(253>238\)\(suy\)\(ra:\)\(\frac{23}{7}>\frac{34}{11}\)
ta quy đồng 23/7 và 34/11 mẫu số chung là 77
\(\frac{23}{7}\)=\(\frac{23.11}{7.11}\)=\(\frac{253}{77}\)
\(\frac{34}{11}\)=\(\frac{34.7}{11.7}\)=\(\frac{238}{77}\) => > \(\frac{253}{77}\)> \(\frac{238}{77}\)
vậy \(\frac{23}{7}\)> \(\frac{34}{11}\)
