a) \(\frac{2525}{2727}=\frac{2525:101}{2727:101}=\frac{25}{27}\)
\(\frac{135135}{500500}=\frac{135135:5005}{500500:5005}=\frac{27}{100}\)
\(\frac{153153153}{170170170}=\frac{153153153:17017017}{170170170:17017017}=\frac{9}{10}\)
b) \(\frac{7}{20}=\frac{7x6}{20x6}=\frac{42}{120}\)

Bài 1 : Các số đó là : \(\frac{35}{60};\frac{46}{60}\)
Bài 2 :
\(\frac{12}{30}=\frac{12:6}{30:6}=\frac{2}{5}\); \(\frac{20}{45}=\frac{20:5}{45:5}=\frac{4}{9}\)
\(\frac{28}{70}=\frac{28:14}{70:14}=\frac{2}{5}\) ; \(\frac{34}{51}=\frac{34:17}{51:17}=\frac{2}{3}\)

a)\(\frac{2525}{2727}\)không rút gọn được. b)\(\frac{7}{20}\) = \(\frac{42}{120}\);\(\frac{23}{30}\) = \(\frac{92}{120}\);\(\frac{34}{40}\) = \(\frac{102}{120}\);\(\frac{53}{60}\) = \(\frac{106}{120}\)
\(\frac{135135}{500500}\)= \(\frac{57027}{100100}\)
\(\frac{135153153}{170170170}\)=\(\frac{45051051}{56723390}\)
a) 2525/2727 =2525:101/2727:101 =25/27
135135/500500 =135135:5005/500500:5005 =27/100
135153153/170170170=135153153:17017017/170170170:17017017=9/10
b) 7/20 =7x6/20x6 =42/120
23/30 =23x4/30x4 =92/120
34/40 =34x3/40x3 =102/120
