\(\frac{2}{5}=\frac{12}{30}=\frac{40}{100}\)
\(\frac{4}{7}=\frac{12}{21}=\frac{20}{35}\)
\(HokT\)
Vì:
\(\dfrac{12}{20}=\dfrac{12:4}{20:4}=\dfrac{3}{5}\)
\(\dfrac{12}{14}=\dfrac{12:2}{14:2}=\dfrac{6}{7}\)
\(\dfrac{18}{21}=\dfrac{18:3}{21:3}=\dfrac{6}{7}\)
\(\dfrac{60}{100}=\dfrac{60:20}{100:20}=\dfrac{3}{5}\)
Vậy \(\dfrac{3}{5}=\dfrac{12}{20}=\dfrac{60}{100}\) ; \(\dfrac{6}{7}=\dfrac{12}{14}=\dfrac{18}{21}\)

\(\frac{2}{5}\Leftrightarrow\frac{14}{35}\)
\(\frac{18}{48}\Leftrightarrow\frac{3}{8}\)
\(\frac{4}{7}\Leftrightarrow\frac{20}{35}\)
\(\dfrac{3}{5}và\dfrac{15}{25}và\dfrac{21}{35};\dfrac{5}{8}và\dfrac{20}{32}\)
\(\dfrac{3}{5}=\dfrac{9}{15}=\dfrac{15}{25}=\dfrac{21}{35}\\ \dfrac{5}{8}=\dfrac{20}{32}\)
a) 1/2
b) 18/17; 17/16; 16/15; 15/14; 14/13; 13/12; 10/9
Nhớ k cho mk nha
a)1/2
b)Vì 18/17 <17/16 <16/15<15/14< 14/13< 13/12< 10/9
Nên, ta có:
18/17; 17/16; 16/15; 15/14; 14/13; 13/12; 10/9.
\(\dfrac{5}{7}=\dfrac{70}{98};\dfrac{2}{5}=\dfrac{14}{35};\dfrac{1}{8}=\dfrac{9}{72};\dfrac{120}{80}=\dfrac{3}{2}\)
\(\dfrac{5}{7}=\dfrac{70}{98}\)
\(\dfrac{2}{5}=\dfrac{14}{35}\)
\(\dfrac{1}{8}=\dfrac{9}{72}\)
\(\dfrac{120}{80}=\dfrac{3}{2}\)
