Ta có:\(\frac{2525}{2727}=\frac{2525:101}{2727:101}=\frac{25}{27}\)
\(\frac{135135}{500500}=\frac{135135:5005}{500500:5005}=\frac{27}{100}\)
\(\frac{153153153}{170170170}=\frac{153153153:17017017}{170170170:17017017}=\frac{9}{10}\)
Vậy ...........
2525/2727=25/27
135135/500500=27/100
153153153/170170170=9/10
