K mk nhé

*Mio*

a) \(\frac{171717}{232323}=\frac{17}{23}\)

b) \(\frac{193193193}{197197197}=\frac{193}{197}\)

#

a) \(\dfrac{17}{23}\)

b) \(\dfrac{193}{197}\)

= 51/63 = 17/21

17

21

515151 / 636363=171717 / 212121= 51 / 63 = 17 /21

nhớ tick cho mình

1313/2323= 1313:101/2323:102= 13/23

515151/636363= 515151:30303/ 636363:30303= 17/21

a/\(\frac{1313}{2323}=\frac{13}{23}\)    b/\(\frac{515151}{636363}=\frac{51}{63}\)  

xog ùi bn tk mk vs, mk đúng thì tk nha thanks ^2

\(\frac{1313}{2323}=\frac{1313:101}{2323:101}=\frac{13}{23}\) ,  \(\frac{515151}{636363}=\frac{515151:10101}{636363:10101}=\frac{51}{63}=\frac{17}{21}\)

làm như bn my là đúng nhé, mk tự làm và ko sao chép 

111111/171717 = 11/17

11/17

\(\frac{111111}{171717}\)=\(\frac{11}{17}\)

k nha

a) \(\frac{171717}{292929}=\frac{171717:10101}{292929:10101}=\frac{17}{29}\)

b) \(\frac{3344}{1212}=\frac{3344:4}{1212:4}=\frac{836}{303}\)

Học tốt nhé

51*10101/31*10101=51/31
