\(\frac{201201}{202202}=\frac{201}{201}\)
rut gon phan so sau
\(\frac{2^{13}+2^5}{2^{10}+2^2}\)
\(\frac{2^{13}+2^5}{2^{10}+2^2}=\frac{2^5\left(2^6+1\right)}{2^2\left(2^8+1\right)}=\frac{2^3.65}{257}=\frac{520}{257}\)

tong cua tu so va mau so cua mot phan so la 4812 sau khi rut gon phan so do ta duoc phan so 5/7 hay tim phan so chua rut gon
Gọi phân số chưa rút gọn là : a/b ( a,b thuộc Z )
=> a+b=4812 và a/b = 5/7
a/b=5/7 => a=5/7.b
=> 4812 = 5/7.b + b = 12/7.b
=> b=2807 ; a = 2005
Vậy phân số chưa rút gọn là : 2005/2807

So Sánh : \(\dfrac{201201}{202202}\)và\(\dfrac{201201201}{202202202}\)
Ta có: \(\dfrac{201201}{202202}=\dfrac{201}{202}\)
\(\dfrac{201201201}{202202202}=\dfrac{201}{202}\)
Do đó: \(\dfrac{201201}{202202}=\dfrac{201201201}{202202202}\)
