Rút gọn phân số:

\(\frac{6}{9}=\frac{6\div3}{9\div3}=\frac{2}{3}\)

\(\frac{10}{48}=\frac{10\div2}{48\div2}=\frac{5}{24}\)

\(\frac{72}{84}=\frac{72\div12}{84\div12}=\frac{6}{7}\)

\(\frac{1212}{3939}=\frac{1212\div303}{3939\div303}=\frac{4}{13}\)

\(\frac{6}{9}=\frac{6:3}{9:3}=\frac{2}{3}\)

\(\frac{18}{48}=\frac{18:2}{48:2}=\frac{9}{24}\)

\(\frac{72}{84}=\frac{72:12}{84:12}=\frac{6}{7}\)

\(\frac{1212}{3939}=\frac{1212:101}{3939:101}=\frac{12}{39}\)

6/9=2/3

18/48=6/16

72/84=6/7

1212/3939=404/1313

\(\dfrac{1212}{3939}=\dfrac{4}{13}\)

1212/3939=4/13

3131/3535=31/35 

tk mình nhé bạn

Thank you vẻy much

1212/3939 = 4/13

3131/3535 = 31/35

tk mình nha

1212/3939=4/13

3131/3535=31/35

k mk nha

\(\dfrac{72\times75}{125\times108}\) = \(\dfrac{36\times2\times25\times3}{25\times5\times36\times3}\) = \(\dfrac{2}{5}\)

\(\dfrac{72}{78}=\dfrac{72:6}{78:6}=\dfrac{12}{13}\)

\(\frac{72}{96}=\frac{72\div24}{96\div24}=\frac{3}{4}\)

72/96 = 72 : 24 / 96 : 24 = 3/4
