a:\(\dfrac{12}{13}\)
b:\(\dfrac{12}{13}\)
c:\(\dfrac{121}{131}\)
a) \(\frac{6}{9}=\frac{6:3}{9:3}=\frac{2}{3}\)
b)\(\frac{10}{48}=\frac{10:2}{48:2}=\frac{5}{24}\)
c)\(\frac{72}{84}=\frac{72:12}{84:12}=\frac{6}{7}\)
d)\(\frac{1212}{3939}=\frac{1212:303}{3939:303}=\frac{4}{13}\)

Rút gọn phân số:
\(\frac{6}{9}=\frac{6\div3}{9\div3}=\frac{2}{3}\)
\(\frac{10}{48}=\frac{10\div2}{48\div2}=\frac{5}{24}\)
\(\frac{72}{84}=\frac{72\div12}{84\div12}=\frac{6}{7}\)
\(\frac{1212}{3939}=\frac{1212\div303}{3939\div303}=\frac{4}{13}\)
bằng 2736 nha
k cho mik ko ko k cũng được nhưng nếu k thì mik cảm ơn
_ \(\frac{7}{9}=\frac{7\times11}{9\times11}=\frac{7\times111}{9\times111}\Rightarrow\frac{7}{9}=\frac{77}{99}=\frac{777}{999}\)
_ \(\frac{13}{15}=\frac{13\times101}{15\times101}=\frac{13\times10101}{15\times10101}\Rightarrow\frac{13}{15}=\frac{1313}{1515}=\frac{131313}{151515}\)
_ \(\frac{20172017}{20072007}=\frac{20172017:10001}{20072007:10001}\Rightarrow\frac{20172017}{20072007}=\frac{2017}{2007}\)
_ \(\frac{123123}{456456}=\frac{123123:1001}{456456:1001}\Rightarrow\frac{123123}{456456}=\frac{123}{456}\)
~ Ủng hộ mk nha!~
\(\frac{1212}{3030}=\frac{2}{5}\)
\(\frac{32032}{48048}=\frac{2}{3}\)
\(\frac{456456}{234234}=\frac{76}{39}\)
\(\frac{1339}{1442}=\frac{13}{14}\)
#Châu's ngốc
121/143=11/13
1212/1414=6/7
123123/456456=123/456=41/152
\(\dfrac{121}{143}=\dfrac{11}{13}\) ; \(\dfrac{1212}{1414}=\dfrac{6}{7}\) ; \(\dfrac{123}{456}=\dfrac{41}{152}\)
