\(C=\dfrac{2495148+2000}{2497170-22}=\dfrac{2467148}{2497148}=1\)
\(C=\dfrac{2022.1234+2000}{1235.2022-22}=\dfrac{2022.\left(1235-1\right)+2000}{1235.2022-22}=\dfrac{1235.2022-2022+200}{1235.2022-22}\)
\(=\dfrac{1235.2022-22}{1235.2022-22}=1\)
gạch 2022 ở tử và mẫu thì đc : 1234+2000/ 1235-22= 3234/ 1213
