\(\frac{4}{6}=\frac{2}{3}\)
\(\frac{18}{27}=\frac{2}{3}\)
\(\Rightarrow\frac{4}{6}=\frac{18}{27}\)
\(\frac{12}{20}=\frac{3}{5}\)
\(\frac{22}{55}=\frac{2}{5}\)
\(\Rightarrow\frac{12}{20}>\frac{22}{55}\)
\(\frac{5}{6}=\frac{10}{12}\)
\(\Rightarrow\frac{5}{6}< \frac{11}{12}\)

\(\dfrac{12}{10}\);\(\dfrac{8}{10}\);\(\dfrac{2}{5}\);\(\dfrac{9}{45}\)
a)\(\dfrac{8}{15}< \dfrac{11}{15}< \dfrac{15}{15}< \dfrac{16}{15}< \dfrac{17}{15}< \dfrac{19}{15}\)
b)\(\dfrac{19}{42}< \dfrac{19}{35}< \dfrac{19}{21}< \dfrac{19}{19}< \dfrac{19}{17}\)
c)\(\dfrac{8}{10}< \dfrac{6}{7}< \dfrac{27}{25}< \dfrac{16}{14}\)
a) 8/15 ; 11/15 ; 15/15 ; 16/15 ; 17/15 ; 19/15
b) 19/42 19/35 ; 19/21 ; 19/19 ; 19/17
c) 8/10 ; 6/7 ; 27/25 ; 16/14
\(\dfrac{2}{3}< \dfrac{4}{5}< \dfrac{5}{6}< \dfrac{9}{10}< \dfrac{14}{15}\)
55/33 ; 37/37 ; 56/64 ; 126/168 ; 12 /39
mik rút gọn xong so sánh bình thường thôi
\(\dfrac{6}{10}=\dfrac{3}{5};\dfrac{12}{15}=\dfrac{4}{5};\dfrac{22}{55}=\dfrac{2}{5}\)
mà 4>3>2
nên \(\dfrac{12}{15}>\dfrac{6}{10}>\dfrac{22}{55}\)
