Rút gọn phân số:
\(\frac{6}{9}=\frac{6\div3}{9\div3}=\frac{2}{3}\)
\(\frac{10}{48}=\frac{10\div2}{48\div2}=\frac{5}{24}\)
\(\frac{72}{84}=\frac{72\div12}{84\div12}=\frac{6}{7}\)
\(\frac{1212}{3939}=\frac{1212\div303}{3939\div303}=\frac{4}{13}\)
\(\frac{6}{9}=\frac{6:3}{9:3}=\frac{2}{3}\)
\(\frac{18}{48}=\frac{18:2}{48:2}=\frac{9}{24}\)
\(\frac{72}{84}=\frac{72:12}{84:12}=\frac{6}{7}\)
\(\frac{1212}{3939}=\frac{1212:101}{3939:101}=\frac{12}{39}\)

nha bn\

\(\dfrac{18}{48}=\dfrac{3}{8}\)
\(\dfrac{72}{3939}=\dfrac{24}{1313}\)
\(\dfrac{1212}{3939}=\dfrac{4}{13}\)
1212/3939=4/13
3131/3535=31/35
tk mình nhé bạn
Thank you vẻy much
\(\dfrac{72\times75}{125\times108}\) = \(\dfrac{36\times2\times25\times3}{25\times5\times36\times3}\) = \(\dfrac{2}{5}\)
\(\dfrac{72}{78}=\dfrac{72:6}{78:6}=\dfrac{12}{13}\)
\(\frac{72}{96}=\frac{72\div24}{96\div24}=\frac{3}{4}\)
72/96 = 72 : 24 / 96 : 24 = 3/4
lưu ý:
/ : là ngăn cách phân số
: chia
\(\frac{72}{84}\)=\(\frac{6}{7}\)
\(\frac{1212}{3939}\)=\(\frac{4}{13}\)
trả lời:
\(\frac{72}{84}=\frac{18}{21}=\frac{6}{7}\)
\(\frac{1212}{3939}=\frac{1212:101}{3939:101}=\frac{12}{39}=\frac{4}{13}\)
học tốt
