Ta có:\(\dfrac{201201}{202202}\)=\(\dfrac{201}{202}\);\(\dfrac{201201201}{202202202}\)=\(\dfrac{201}{202}\)
=>\(\dfrac{201}{202}\)=\(\dfrac{201}{202}\)
=> \(\dfrac{201201}{202202}\)=\(\dfrac{201201201}{202202202}\)
Vậy: \(\dfrac{201201}{202202}\)=\(\dfrac{201201201}{202202202}\)

Ta có:
201201/202202=201/202
201201201/202202202=201/202
Vì 201/202=201/202
=> 201201/202202=201201201/202202202
