\(\frac{77}{176}=\frac{77:11}{176:11}=\frac{7}{16}\)                              ;                               \(\frac{232323}{474747}=\frac{232323:10101}{474747:10101}=\frac{23}{47}\)

       \(\frac{376376}{159159}=\frac{376376:1001}{159159:1001}=\frac{376}{159}\)                ;                    \(\frac{9\cdot8\cdot5}{24\cdot15}=\frac{9\cdot8\cdot5}{8\cdot3\cdot3\cdot5}=\frac{9\cdot8\cdot5}{8\cdot9\cdot5}=1\)

\(24m=\frac{24}{1000}km=\frac{3}{125}km.\)

6 yến = \(\frac{6}{100}\)tấn = \(\frac{3}{50}\)tấn.

------------------------------------------------------------------------

\(\frac{1515}{1717}=\frac{1515\div101}{1717\div101}=\frac{15}{17}\)

24m = \(\frac{24}{1000}\)km = \(\frac{3}{125}\)km

6 yến = \(\frac{6}{100}\)tấn = \(\frac{3}{50}\)tấn

\(\frac{1515}{1717}\)= \(\frac{15}{17}\)

24m=24/1000km=3/125km

6 yến=6/100 tấn=3/50 tấn

1515/1717 = 15/17

giup ik mà :((
 

1717/2121=17/21

232323/191919=23/19

Tự chép đề bài nhé

=\(\frac{11.11.25.3.65.2.169}{3.13.2.30.11.18.11}\)

=\(\frac{25.65.13.13}{13.30.18}\)

=\(\frac{5.5.65.13.13}{13.6.5.18}\)

=\(\frac{5.65.13}{6.18}\)

=\(\frac{65.65}{108}\)

tự tính tiếp

\(\frac{121.75.130.169}{39.60.11.198} \)​= \(\frac{11^2.5^2.3.13.5.2.13^2}{3.13.2^2.3.5.11.2.3^2}\)

                                      = \(\frac{11.5^2.13^2}{2^2.3^3}\)

Mình ko hiểu cho lắm !!!*.*😕😦

\(\frac{124}{237}\)

124242423/237373735= 123/235 
-kết quả đúng nhất-

\(=\frac{123}{235}\)

A) 17/23

B) 193/197

K mk nhé

*Mio*

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

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

#

a) \(\dfrac{17}{23}\)

b) \(\dfrac{193}{197}\)

Chỉ có 1 kiểu câu rút gọn thôi nhé bạn 

ok chị

61/101

61/101 hay0.6

3050/5050=3050:50/5050:50=61/101

                   Đáp số : 61/101

\(\frac{232323}{515151}=\frac{23}{51}.\)

23/51

232323/515151=(232323/10101)/(515151/10101)=23/51
