\(\dfrac{12}{18}=\dfrac{12:6}{18:6}=\dfrac{2}{3}\)
\(\dfrac{49}{21}=\dfrac{49:7}{21:7}=\dfrac{7}{3}\)
\(\dfrac{15}{35}=\dfrac{15:5}{35:5}=\dfrac{3}{7}\)
\(\dfrac{26}{34}=\dfrac{26:2}{34:2}=\dfrac{13}{17}\)
\(\dfrac{11}{121}=\dfrac{11:11}{121:11}=\dfrac{1}{11}\)
\(\dfrac{12}{18}=\dfrac{12:6}{18:6}=\dfrac{2}{3};\dfrac{49}{21}=\dfrac{49:7}{21:7}=\dfrac{7}{3};\dfrac{15}{35}=\dfrac{15:5}{35:5}=\dfrac{3}{7};\dfrac{26}{34}=\dfrac{26:2}{34:2}=\dfrac{13}{17};\dfrac{11}{121}=\dfrac{11:11}{121:11}=\dfrac{1}{11}\)
121/143=11/13
1212/1414=6/7
123123/456456=123/456=41/152
\(\dfrac{121\times75\times130\times169}{39\times60\times11\times198}\)
\(=\dfrac{25\times169}{6\times18}\)
\(=\dfrac{4225}{108}\)
cảm ơn bạn nhé
