k mik nha bn

ngu nhu con cho a 

a,1/3                       b,1/2                                 c,5/9                                                     d,25/93

bằng 23/49 nhé mình với

23/49 nha bạn

TL

\(\frac{232323}{494949}=\frac{23.10101}{49.10101}\)

\(=\frac{23}{49}\)

HT

\(\dfrac{23}{49}\)

=23/49 nha

má ơi sao mà giải đc

\(\dfrac{1515}{2727}=\dfrac{1515:303}{2727:303}=\dfrac{5}{9}\)

Chia tử vào mẫu cho 101 ta có ps tối giản là: 

15/17

\(\dfrac{1515}{2727}=\dfrac{1515:303}{2727:303}=\dfrac{5}{9}\)

\(\frac{232323}{494949}=\frac{232323:10101}{494949:10101}=\frac{23}{49}\)

\(\frac{204204}{217217}=\frac{204204:1001}{217217:1001}=\frac{204}{217}\)

\(\frac{171171171}{180180180}=\frac{171171171:9009009}{180180180:9009009}=\frac{19}{20}\)

\(\frac{232323}{494949}=\frac{232323:10101}{494949:10101}=\frac{23}{49}\)

\(\frac{204204}{217217}=\frac{204204:1001}{217217:1001}=\frac{204}{217}\)

\(\frac{171171171}{180180180}=\frac{171171171::9009009}{180180180:9009009}=\frac{19}{20}\)

Không.Rút gọn được bạn nhé

`117/234=(117:117)/(234:117)=1/2`

`90/126=(90:18)/(126:18)=5/7`

`162162/345345=(162162:3003)/(345345:3003)=54/115`

\(\dfrac{117}{234}\)= \(\xrightarrow[234:117]{117:117}\) = \(\dfrac{1}{2}\)                                    \(\dfrac{162162}{345345}\) = \(\xrightarrow[345345:3003]{162162:3003}\) =\(\dfrac{54}{115}\)

\(\dfrac{90}{126}\)= \(\xrightarrow[126:18]{90:18}\) = \(\dfrac{5}{7}\)                                     

\(\dfrac{117}{234}=\dfrac{1}{2}\)

Rút gọn

\(\frac{1313}{2727}=\frac{13\cdot101}{27\cdot101}=\frac{13}{27}\)

\(\frac{151515}{232323}=\frac{15\cdot10101}{23\cdot10101}=\frac{15}{23}\)

\(\frac{123123}{456456}=\frac{123\cdot1001}{456\cdot1001}=\frac{123}{456}=\frac{41\cdot3}{152\cdot3}=\frac{41}{152}\)

hok tốt

==.== mk làm vậy thôi , nếu sai thì thông cảm cho mk nha ...
