373737 và 535353 chia cho 10101 = 37 và 53
3737 và 5353 chia cho 101 = 37 và 53
\(\frac{3737}{5353}=\frac{37}{53}\)
\(\frac{373737}{535353}=\frac{37}{53}\)
Vì \(\frac{37}{53}=\frac{37}{53}\)nên \(\frac{3737}{5353}=\frac{373737}{535353}\)
Ta có:
\(\frac{3737}{5353}=\frac{37x101}{53x101}=\frac{37}{53}\)
\(\frac{373737}{535353}=\frac{37x10101}{53x10101}=\frac{37}{53}\)
Vì \(\frac{37}{53}=\frac{37}{53}\)
=> \(\frac{3737}{5353}=\frac{373737}{535353}\)

\(\frac{2323}{2525}+\frac{212121}{252525}\)
\(=\frac{23\times101}{25\times101}+\frac{21\times10101}{25\times10101}\)
\(=\frac{23}{25}+\frac{21}{25}\)
\(=\frac{44}{25}\)
\(\frac{2323}{2525}+\frac{212121}{252525}\)
\(=\)\(\frac{23}{25}+\frac{21}{25}\)
\(=\frac{44}{25}\)
\(\frac{767676}{252525}+\frac{2424}{2525}=\frac{76}{25}+\frac{24}{25}\)
\(=\frac{76+24}{25}=\frac{100}{25}=4\)
a) \(\dfrac{252525}{666666}=\dfrac{25.10101}{66.10101}=\dfrac{25}{66}\)
⇒\(\dfrac{25}{66}=\dfrac{252525}{666666}\)
b: \(\dfrac{23}{24}=1-\dfrac{1}{24}\)
\(\dfrac{24}{25}=1-\dfrac{1}{25}\)
mà \(-\dfrac{1}{24}>-\dfrac{1}{25}\)
nên \(\dfrac{23}{24}>\dfrac{24}{25}\)
a: \(\dfrac{25}{66}=\dfrac{252525}{666666}\)
b: \(\dfrac{23}{24}=1-\dfrac{1}{24}\)
\(\dfrac{24}{25}=1-\dfrac{1}{25}\)
mà \(-\dfrac{1}{24}< -\dfrac{1}{25}\)
nên \(\dfrac{23}{24}< \dfrac{24}{25}\)
\(\frac{25}{53}\) ; \(\frac{2525}{5353}\) : \(\frac{252525}{535353}\)
