Bài 2:
a: \(\dfrac{1}{4};\dfrac{2}{5}\)
\(\dfrac{1}{4}=\dfrac{1\cdot5}{4\cdot5}=\dfrac{5}{20}\)
\(\dfrac{2}{5}=\dfrac{2\cdot4}{5\cdot4}=\dfrac{8}{20}\)
\(\dfrac{2}{3};\dfrac{7}{8}\)
\(\dfrac{2}{3}=\dfrac{2\cdot8}{3\cdot8}=\dfrac{16}{24}\)
\(\dfrac{7}{8}=\dfrac{7\cdot3}{8\cdot3}=\dfrac{21}{24}\)
\(\dfrac{3}{4};\dfrac{5}{6}\)
\(\dfrac{3}{4}=\dfrac{3\cdot3}{4\cdot3}=\dfrac{9}{12}\)
\(\dfrac{5}{6}=\dfrac{5\cdot2}{6\cdot2}=\dfrac{10}{12}\)
b: \(\dfrac{1}{3};\dfrac{7}{9}\)
\(\dfrac{1}{3}=\dfrac{1\cdot3}{3\cdot3}=\dfrac{3}{9}\)
\(\dfrac{7}{9}=\dfrac{7\cdot1}{9\cdot1}=\dfrac{7}{9}\)

\(\dfrac{3838}{4040}=\dfrac{3838:101}{4040:101}=\dfrac{38}{40}=\dfrac{38:2}{40:2}=\dfrac{19}{20}\)
\(\dfrac{119119}{123123}=\dfrac{119119:1001}{123123:1001}=\dfrac{119}{123}\)
A:\(\frac{1919}{7373}=\frac{1919:101}{7373:101}=\frac{19}{73}\)
\(\frac{454545}{818181}=\frac{454545:10101}{818181:10101}=\frac{45}{81}=\frac{5}{9}\)
\(\frac{234234}{361361}=\frac{234234:1001}{361361:1001}=\frac{234}{361}\)
B: \(\frac{17}{18}=\frac{1}{2}+\frac{1}{3}+\frac{1}{9}\)
123123/132132=41/44(chia cả tử và mẫu cho 3003)
chính xác rồi đấy,các bạn cho mình nhé!
mẫu số và tử số chia cho 273 đc phân số \(\frac{451}{1332}\)
\(\frac{98}{100}=\frac{49}{50}\)
\(\frac{123123}{234234}=\frac{41}{78}\)
\(\frac{20182018}{20152019}\approx1.001488635\)
