Ta có :
\(\frac{1515}{1717}\) = \(\frac{1515:101}{1717:101}\)= \(\frac{15}{17}\)
Vậy ta được phân số : \(\frac{15}{17}\)

\(\frac{1717}{3232}=\frac{17}{32};\frac{1515}{1616}=\frac{15}{16}\)
![](https://rs.olm.vn/images/avt/0.png?1311)
\(\frac{1515}{1717}\) \(=\) \(\frac{1515:101}{1717:101}\) \(=\) \(\frac{15}{17}\)
\(\frac{625}{600}\) \(=\) \(\frac{625:25}{600:25}\) \(=\) \(\frac{25}{24}\)
Chúc bạn học tốt !

\(24m=\frac{24}{1000}km=\frac{3}{125}km.\)
6 yến = \(\frac{6}{100}\)tấn = \(\frac{3}{50}\)tấn.
------------------------------------------------------------------------
\(\frac{1515}{1717}=\frac{1515\div101}{1717\div101}=\frac{15}{17}\)
24m = \(\frac{24}{1000}\)km = \(\frac{3}{125}\)km
6 yến = \(\frac{6}{100}\)tấn = \(\frac{3}{50}\)tấn
\(\frac{1515}{1717}\)= \(\frac{15}{17}\)

Bài 1:
18/27=2/3
35/25=7/5
54/72=3/4
78/66=13/11
92/100=23/25
75/125=3/5
126/165=42/55
150/300=1/2
1717/1515=17/15

1313/1717 = ( 1313 :101)/(1717:101)=13/17
171717/191919=(171717:10101)/(191919:10101)=17/19
231231/343343=(231231:7007)/(343343:7007)=33/49
373737/494949=(373737:10101)/(494949:10101)=37/49

=\(\frac{17}{15}\)
\(\frac{1717}{1515}=\frac{1717:101}{1515:101}=\frac{17}{15}\)
vậy phân số \(\frac{1717}{1515}\)sau khi rút gọn là \(\frac{17}{15}\)
