Chứng minh rằng:

\(\frac{27}{31}=\frac{2727}{3131}=\frac{272727}{313131}\)

Answer 1

\(\frac{27}{31}=\frac{2727}{3131}=\frac{272727}{313131}\)

\(\frac{27}{31}=\frac{27.101}{31.101}=\frac{27.10101}{31.10101}\)

\(\frac{27}{31}=\frac{27}{31}=\frac{27}{31}\)

\(\Rightarrow\frac{27}{31}=\frac{2727}{3131}=\frac{272727}{313131}\)

Answer 2

\(\frac{27}{31}=\frac{2727}{3131}=\frac{272727}{313131}\)

\(\frac{27}{31}=\frac{27\cdot101}{31\cdot101}=\frac{27\cdot10101}{31\cdot10101}\)

\(\Rightarrow\frac{27}{31}=\frac{2727}{3131}=\frac{272727}{313131}\)
