Ấy chết sai !

\(\frac{272727}{323232}=\frac{272727\div10101}{323232\div10101}=\frac{27}{32}\)

Đáp số : \(\frac{27}{32}\)

Ta có: \(\frac{272727}{323232}=\frac{272727:10101}{323232:10101}=\frac{27}{32}\)

\(\frac{272727}{323232}=\frac{27\times10101}{32\times10101}=\frac{27}{32}\)

\(\frac{430430}{560560}=\frac{10010\times43}{10010\times56}=\frac{43}{56}\)

ta co \(\frac{272727}{323232}=\frac{27}{32};\frac{430430}{560560}=\frac{43}{56}\)

vi 27/32>43/56

=>       ..............

\(\frac{121212}{131313}=\frac{12.10101}{13.10101}=\frac{12}{13}\)

12/13

không quy đồng thì rút gọn

121212/131313=12/13

vậy 12/13>12/18

121212/131313=12/13.ve nha hoc bai nhe da tung hoc roi

het

\(\frac{121212}{141414}\times\frac{1313}{1212}\times\frac{2424}{2424}\)

\(=\frac{6}{7}\times\frac{13}{12}\times1\)

\(=\frac{13}{14}\)

~ Hok tốt ~

kết quả là ; 1313/141414

sau nhắc mik

Ta có: 15x14-1/15x13+14=15x13+15-1/15x13+14=15x13+14/15x13+14=1 

\(\frac{15x14-1}{15x13+14}\)

\(\frac{15x13}{15x13+14}\)=\(\frac{1}{14}\)

a,

\(=\frac{1+2+3+4+5+6+7+8+9}{10}=\frac{45}{10}=\frac{9}{2}\)

b,\(=9\times\left(\frac{26\times10101}{27\times10101}+\frac{8\times11111}{9\times11111}\right)=9\times\left(\frac{26}{27}+\frac{8}{9}\right)=9\times\frac{50}{27}=\frac{50}{3}\)

k cho mk nha!!!!!!!!!!!!!

Mk cần gấp các bạn ơi !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!?

121212/131313 = 12/13 

=> 12/13 < 12/ 18 

Vậy .......... 

k mình nha

121212/131313

=12/13

12/13>12/18

=> 121212/131313>12/18

k minh nha

121212x121212=14692348944

k mình nha !

121212 x 121212 = 14692348944

191919/272727 = 19 x 10101 / 27 x 10101 = 19 /27
