Ta có : \(\frac{45}{65}=\frac{9}{13};\frac{48}{52}=\frac{12}{13};\frac{1010}{1313}=\frac{10}{13}\)
\(=>\frac{9}{13}< \frac{10}{13}< \frac{12}{13}\)
Ta có: \(\frac{45}{65}=\)\(\frac{9}{13}\); \(\frac{48}{52}=\frac{12}{13}\); \(\frac{1010}{1313}=\frac{10}{13}\) => \(\frac{9}{13}< \frac{10}{13}< \frac{12}{12}\) hay \(\frac{45}{65}< \frac{1010}{1313}< \frac{48}{52}\)
Ta có:
\(\frac{45}{65}=\frac{45\div5}{65\div5}=\frac{9}{13}\)
\(\frac{48}{52}=\frac{48\div4}{52\div4}=\frac{12}{13}\)
\(\frac{1010}{1313}=\frac{1010\div101}{1313\div101}=\frac{10}{13}\)
\(\Rightarrow\frac{9}{13}< \frac{10}{13}< \frac{12}{13}\)
