\(\frac{2323}{2525}+\frac{212121}{252525}\)
\(=\frac{23\times101}{25\times101}+\frac{21\times10101}{25\times10101}\)
\(=\frac{23}{25}+\frac{21}{25}\)
\(=\frac{44}{25}\)
\(\frac{2323}{2525}+\frac{212121}{252525}\)
\(=\)\(\frac{23}{25}+\frac{21}{25}\)
\(=\frac{44}{25}\)

ta có: \(\frac{1717}{2525}=\frac{17}{25}\)
\(\frac{515151}{727272}=\frac{51}{72}=\frac{17}{24}>\frac{17}{25}\)
\(\Rightarrow\frac{1717}{2525}< \frac{515151}{727272}\)

\(\frac{1717}{2525}=\frac{17}{25};\frac{515151}{727272}=\frac{51}{72}\)
Ta có : \(\frac{17}{25}
\(\frac{1717}{2525}=\frac{17}{25}\)
\(\frac{515151}{727272}=\frac{17}{24}\)
Cùng tử, ta có : 25 > 24
=> \(\frac{17}{25}

\(\frac{1212}{1515}:\frac{2727}{2525}\)
\(=\frac{1212}{1515}x\frac{2525}{2727}\)
\(=\frac{20}{27}\)
Chúc Học tốt
\(\frac{1212}{1515}:\frac{2727}{2525}=\frac{1212}{1515}x\frac{2525}{2727}=\frac{12x101}{15x101}x\frac{25x101}{27x101}=\frac{12x25}{15x27}=\frac{3x4x5x5}{3x5x27}=\frac{4x5}{27}=\frac{20}{27}.\)
