Cô xinh phết :>
\(a,\dfrac{-2}{3};\dfrac{-3}{12};\dfrac{-1}{-6};\dfrac{3}{4}\\ c,\dfrac{3}{-4}-\dfrac{1}{2};0;\dfrac{3}{10};\dfrac{-2}{-5}\\ b,-1;\dfrac{-7}{9};\dfrac{-1}{3};0;\dfrac{-1}{-4};\dfrac{5}{12}\\ d,\dfrac{23}{-25};\dfrac{-7}{10};\dfrac{-2}{5}\dfrac{17}{-50}\dfrac{-37}{-150}\)
a) \(\dfrac{3}{4};\dfrac{-3}{12};\dfrac{-2}{3};\dfrac{-1}{-6}\)
\(\dfrac{3}{4}=\dfrac{9}{12}\) \(;\dfrac{-2}{3}=\dfrac{-8}{12}\) \(;\dfrac{-1}{-6}=\dfrac{1}{6}=\dfrac{2}{12}\)
\(\dfrac{-3}{12};\dfrac{-2}{3};\dfrac{-1}{-6};\dfrac{3}{4}\)
b) \(\dfrac{5}{12};0;\dfrac{-7}{9};-1;\dfrac{-1}{-4};\dfrac{-1}{3}\)
\(\dfrac{5}{12}=\dfrac{15}{36}\)
\(\dfrac{-7}{9}=\dfrac{-28}{36}\)
\(\dfrac{-1}{-4}=\dfrac{1}{4}=\dfrac{9}{36}\)
\(\dfrac{-1}{3}=\dfrac{-12}{36}\)
\(-1;\dfrac{-7}{9};\dfrac{-1}{3};0;\dfrac{-1}{-4}\)\(;\dfrac{5}{12}\)
giúp với giúp với giúp e với ạ. e cảm ơn
