1) Ta có: \(\frac{179}{197}<1;\frac{971}{917}>1\)
=> \(\frac{179}{197}<1<\frac{971}{917}\)
=> \(\frac{179}{197}<\frac{971}{917}\)
2) Ta có: \(\frac{183}{184}<1;\frac{184}{183}>1\)
=> \(\frac{183}{184}<1<\frac{184}{183}\)
=> \(\frac{183}{184}<\frac{184}{183}\)
Câu 1:
1) 179/197 và 971/917
Ta có:
\(1-\frac{179}{197}=\frac{18}{197}\)
\(1-\frac{971}{917}=\frac{-54}{917}\)
Mà \(\frac{-54}{917}<\frac{18}{197}\)
\(\Rightarrow\frac{971}{917}<\frac{179}{197}\)
Câu 2:
Ta có:
\(1-\frac{183}{184}=\frac{1}{184}\)
\(1-\frac{184}{183}=\frac{-1}{183}\)
Mà:\(\frac{-1}{183}<\frac{1}{184}\)
\(\Rightarrow\frac{184}{183}<\frac{183}{184}\)
