\(\frac{45}{117}=\frac{45\div3}{117\div3}=\frac{15}{39}=\frac{15\div3}{39\div3}=\frac{5}{13}\)

T I C K cho mình nhé !

Chúc bạn học tốt.

😁😁😁

\(\dfrac{65}{117}=\dfrac{65:13}{117:13}=\dfrac{5}{9}\)

\(\dfrac{152}{114}=\dfrac{152:38}{114:38}=\dfrac{4}{3}\)

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

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

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

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

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

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

\(\dfrac{90}{126}=\dfrac{5}{7}\)

\(\dfrac{162162}{345345}=\dfrac{54}{115}\)

bằng 3\2 bạn nhé

91/117 = 7/9

182/224 =13/16

    =112/144  và   117/144

75/200 = 3/8                                                            36/84 = 3/7

34/51 = 2/3                                                               117/243 = 13/27

\(\frac{75}{200}\)=\(\frac{3}{8}\); \(\frac{34}{51}\)=\(\frac{2}{3}\);\(\frac{36}{84}\)=\(\frac{3}{7}\); \(\frac{117}{243}\)=\(\frac{13}{27}\)
