\(\frac{151515}{353535}=\frac{151515\div10101}{353535\div10101}=\frac{15}{35}\)

Rút gọn là \(\frac{3}{7}\)nhé 

5/7  nha bạn

tích cho em

\(\frac{252525}{484848}=\frac{252525:10101}{484848:10101}=\frac{25}{48}\)

Dễ

\(\frac{252525}{484848}\)=\(\frac{25}{48}\)

Đs \(\frac{25}{48}\)

Quy đồng giúp vs 2phan3 ;4phan5 và 7phan 10

252525 / 383838 = 25 / 38.

\(\frac{252525}{383838}=\frac{252525:10101}{383838:10101}=\frac{25}{38}\)

25/38

Tớ chắc chắn

Trl :

= 25/53 nha bn

:>

252525 / 535353 = 25 x 10101 / 53 x 10101 = 25 / 53

Ta có : 252525 = 25 . 10101      ( 1 ) 

          : 535353 = 53 . 10101       ( 2 ) 

Từ ( 1 ) ( 2) => ta có : \(\frac{252525}{535353}=\frac{25.10101}{53.10101}=\frac{25}{53}\)

Vậy \(\frac{252525}{535353}=\frac{25}{53}\)

\(\frac{252525}{373737}=\frac{252525:10101}{373737:10101}=\frac{25}{37}\)

\(\frac{272727}{353535}=\frac{272727:10101}{353535:10101}=\frac{27}{35}>\frac{27}{37}>\frac{25}{37}\)

vậy \(\frac{252525}{373737}

\(\frac{252525}{373737}=\frac{25.10101}{37.10101}=\frac{25}{37}=\frac{875}{1295}\)

\(\frac{272727}{353535}=\frac{27.10101}{35.10101}=\frac{27}{35}=\frac{999}{1295}\)

Vì \(\frac{875}{1295}

\(\frac{252525}{373737}=\frac{252525:10101}{373737:10101}=\frac{25}{37};\frac{272727}{353535}=\frac{272727:10101}{353535:10101}=\frac{27}{35}\)

=>25/37<27/35

\(\frac{131313}{252525}\)\(=\)\(\frac{131313:10101}{252525:10101}\)\(=\)\(\frac{13}{25}\)

vậy nha

bằng 1/3 bạn nhé . k cho mình nhé

\(\frac{252525}{757575}=\frac{252525:252525}{757575:252525}=\frac{1}{3}\)

\(\frac{252525}{757575}=\frac{252525:252525}{757575:252525}=\frac{1}{3}\)

Đáp số : 1/3

1/3 nhé

Hok tốt 

\(\frac{252525}{757575}\)=\(\frac{252525}{252525\chi3}\)=\(\frac{1}{3}\)

thì bn quy đòng mẫu số hai phân số ra

rùi xem p/s nào có tử số lớn hơn thì lớn hơn 

\(\frac{181818}{242424}=\frac{181818:10101}{242424:10101}=\frac{18}{24}=\frac{18:6}{24:6}=\frac{3}{4}\)

\(\frac{181818}{242424}=\frac{181818\div10101}{242424\div10101}=\frac{18}{24}\)

\(\frac{252525}{353535}=\frac{252525\div10101}{353535\div10101}=\frac{25}{35}\)

Ta có : \(\frac{18}{24}=\frac{18\times35}{24\times35}=\frac{630}{840};\frac{25}{35}=\frac{25\times24}{35\times24}=\frac{600}{840}\)

Vì \(\frac{630}{840}>\frac{600}{840}\)nên \(\frac{181818}{242424}>\frac{252525}{353535}\)
