k chị nha!

11/12=1/2 , 36/10=18/5 , 75/36 = 25/12 , 14/28 = 1/2 , 48/30 = 8/5

1/2;18/5;25/12;1/2;24/15

\(\dfrac{11}{22}\)=\(\dfrac{1}{2}\)

k cho minh nhe

45/60 =3/4

15/36 = 5/12

105/75 = 7/5

72/100 = 18/25

45/60 = 3/4

\(\dfrac{6}{9}\) = \(\dfrac{6:3}{9:3}\) = \(\dfrac{2}{3}\)                    \(\dfrac{24}{36}\) = \(\dfrac{24:12}{36:12}\) = \(\dfrac{2}{3}\)

wow đúng hết hâm mộ quá

 Ta có: \(\frac{{12}}{{ - 24}} = \frac{{12:12}}{{ - 24:12}} = \frac{1}{{ - 2}}\)

\(\frac{{ - 39}}{{75}} = \frac{{ - 39:3}}{{75:3}} = \frac{{ - 13}}{{25}}\)

\(\frac{{132}}{{ - 264}} = \frac{{132:132}}{{ - 264:132}} = \frac{1}{{ - 2}}\).

2/5,2/3,3/7,1/3,12/25

5/10= 1/2

\(\dfrac{5}{10}=\dfrac{1}{2}\);\(\dfrac{12}{36}=\dfrac{1}{3}\);\(\dfrac{9}{72}=\dfrac{1}{8}\);\(\dfrac{75}{300}=\dfrac{1}{4}\);\(\dfrac{15}{35}=\dfrac{3}{7}\);\(\dfrac{4}{100}=\dfrac{1}{25}\)

1/2   1/3  1/8
rồi anh rút gọn rồi

27/36=3/4                                       75/100=3/4

26/91=2/7                                         1515/1919=15/19

27/36=3/4                                       75/100= 3/4

26/91=   2/7                                      1515/1919= 15/19
