a)\(\frac{121212}{131313}=\frac{121212:10101}{131313:10101}=\frac{12}{13}\)

b)\(\frac{2^3\cdot3^4}{2^2\cdot3^2\cdot5}=\frac{2^2\cdot3^2\cdot3^2.2}{2^2\cdot3^2\cdot5}=\frac{3^2\cdot2}{5}=\frac{9\cdot2}{5}=\frac{18}{5}\)

a) 121212/131313 = 121212 : 1010/131313 : 1010 = 12/13.

TL

\(\frac{6}{7}< \frac{121212}{131313}\)

nha bn

HT

TL :

Ta có : 121212/131313 = 12/13

Lại có : 6/7 = 78/91

12/13 = 84/91

Mà 78/91 < 84/91

=> 6/7 < 121212/131313

HT

`111111/131313=(111111:10101)/(131313:10101)=11/13`

11/13

\(\dfrac{111111}{131313}\) = \(\dfrac{111111}{131313}\): \(\dfrac{101}{101}\) = \(\dfrac{11}{13}\)

\(\dfrac{11}{13}\) không chia hết cho số nào khác trừ số 1.

123123/132132=41/44(chia cả tử và mẫu cho 3003)

chính xác rồi đấy,các bạn cho mình nhé!

=41/44

TICH CHO MIK NHA!!!!!!!!!!!!!!

 \(\frac{41}{44}\)

bn rút cho 1001 bằng 12/39, rut tiếp cho 3 4/13

\(\frac{121212}{393939}=\frac{4}{13}\)

nhé bn 

chúc bn hc tốt
